Introduction

Electric cars are becoming quite popular nowadays with the continuous increase on fuel prices. These cars not only economical, they are also better for environment, they do not emit carbon dioxide. It is an accepted worldwide fact that in our near future, we will be seeing a lot more of these cars. 1.1 What Is Fuzzy Logic?

Fuzzy Logic: | a form of mathematical logic in which truth can assume a continuum of values between 0 and 1. | | Princeton Web Dictionary

Fuzzy logic is a form of logic with more than two values. Formally it can be called as probabilistic logic and it simply deals with approximated values rather than exact ones; as in daily language, it includes grays along with black and white. It is also accepted as a problem solving control system methodology.
Fuzzy logic is a type of logic that recognizes more than only true and false values. With fuzzy logic, variables can be represented with degrees of truthfulness and falsehood. As an example ‘today is sunny’ statement can be used; this statement, might be 100% true if there are absolutely no clouds, 80% true if there are a few clouds, 50% true if it's partly cloudy and 0% true if it rains all day.
Advantages of fuzzy logic can be listed as: * Fuzzy logic is easy to understand. * Fuzzy logic is flexible. * Fuzzy logic is based on natural language. * Fuzzy logic can model nonlinear functions of arbitrary complexity.
Advantages of fuzzy logic continued: * Fuzzy logic is tolerant of imprecise data. * Fuzzy logic can be blended with conventional control techniques. * Fuzzy logic can be built on top of the experience of experts. * Fuzzy logic does not solve new problems. It uses new methods to solve everyday problems. * Mathematical concepts within fuzzy reasoning are very simple.

Speed Control of Induction Motor Using Fuzzy Logic and Pll

...parameters that are obtained from it are thereby approximate. This leads us to more advanced control methods to meet the real demand. To overcome the complexities of conventional controllers, fuzzy logic controller have been implemented in many motor applications. A Fuzzy Logic Controller (FLC) is incorporated for combination with Phase Locked Loop (PLL) for precise and robust speed of induction motor. The fuzzy logic controller is used to pull the motor speed into the locking range of PLL. When the speed error is between the set point speed and the measured speed is larger than the preset value, the motor speed is incremented or decremented by the fuzzy logic controller towards the PLL locking range. In order to achieve excellent speed regulation, PLL control replaces the FLC when speed error is within the locking range of PLL. When the system operates in the phase locked loop, the speed of motor is locked by a reference frequency. Synchronization of motor speed to a very accurate reference frequency warrants that the motor speed will not drift due to temperature or component wear. Thus, a precise speed control of induction motor operation is achieved. 1.2 Objective The main objective of this project is design a speed control system of the induction motor based on fuzzy logic controller implemented with phase locked loop controller, employing the scalar control model. The voltage and frequency input to the induction motor are to be controlled in order to......

...Penelope Ramirez BUS 230 Bill Forte June 2, 2013 Fuzzy Hugs Maintaining a high-quality, low-cost strategy is a philosophy many companies try to pursue in today’s competitive market. Not everyone can achieve that without hard work, massive time and other resources dedicated to ensure methods. Keeping a diverse work force is what we strive for. It allows employees from different backgrounds, different educational and occupational experience to collaborate and reach common goals. Adverse impact and validity are among the topics in this analysis; as follows. Effectively using information to make business decisions is vital to a company’s success. Analyzing data can help organizations determine if they have a high quality and talented workforce that can perform, meet objectives, and implement strategy. Successful data analysis can also help with hiring, training, and planning decisions. Yet, this same information can be used for decisions on down-sizing, and layoffs. It is important and fundamental to have measurements t assist in making decisions. The problem we face is deciding between two assessment systems, both of which are relatively expensive. As Fuzzy Hugs pursuing and maintaining a high quality low cost strategy is the business model. Furthermore, underperforming manufacturing employees cannot be afforded to be employed given the lean staffing model. The first system brought forth by Fuzzy Hugs has high validity and predicts job success well, but it results in......

...Logical Concepts an overview What is logic? •  Logic is the science of reasoning, •  which is to say: the academic discipline that investigates reasoning. What is reasoning? •  reasoning is inferring (deducing) •  to infer is to draw conclusions (output) from a premise or set of premises (input). An Example of Reasoning You see smoke And you infer That there is fire (input) (deduce) (output) Another example of Reasoning You count 19 people in a group; which originally had 20 people in it; and you infer that someone is missing (input) (input) (deduce) (output) The Basic Idea Logic evaluates reasoning in terms of arguments. What is an argument? •  The word “argument” can mean many different things depending on the context. •  But for the purposes of logic, the term “argument” means something very specific: What is an argument? •  an argument is a collection of statements, one of which is designated as the conclusion, and the remainder of which are designated as the premises. •  Important note: premises are always intended to provide support or evidence for the conclusion, but they don't always succeed. (It’s still an argument either way.) What is a statement? •  A statement is a declarative sentence, •  i.e., a sentence that is capable of being true or false. •  For example: The door is closed. •  Other kinds of sentence are not capable of being true or false: •  Interrogative sentences are inquiries for information: Is the......

...Lógica Fuzzi Americana – 2014 Resumo Considerando os problemas reais que cercam a sociedade hoje tanto nas indústrias, no comércio ou mesmo no dia a dia das pessoas, fica claro a ausência de certezas absolutas quanto a alguns aspectos. Heisenberg em 1927 já falava sobre o princípio da incerteza que serviu como alicerce principal da teoria quântica. Este princípio mais tarde iria auxiliar no desenvolvimento da lógica fuzzy, onde sua forma de raciocinar é muito semelhante ao modelo de raciocínio humano, baseado em aproximações e cercado de incertezas e suposições. Esses algoritmos são amplamente utilizados atualmente em diversas áreas como: robótica, automação de linhas de produção, simulações financeiras entre outras. O sistema lógico apresentado pela lógica fuzzy quando aplicado vai além do raciocínio booleano, pois busca atribuir graus para os elementos em questão de forma que a resposta contido ou não contido somente, não satisfaz e busca-se saber o quão contido ou o quão não contido esta determinado elemento.

...Part one of the video opens up by telling viewers that Aristotle is credited with formalizing logic as a discipline. Viewers are directed to the aspect of what arguments are in the area of logic. Arguments are not heated exchanges or personal assaults, but however they are a group of statements. Statements are sentences capable of being true or false. An example of a statement is saying, “All cats are vicious animals.” The next topic that is brought up in part one of the video is the subject of inference. Inference is the reasoning process of an argument. Inference can be explicit (using premise and/or conclusion indicator words) and implicit (the reader has to catch the inference). Finally the video concludes with the point that there are four non-inferences commonly mistaken for arguments these are: advice, assertion, reports, and explanations. Part two of the formal logic video is the topic of inference. As stated in the early video inference is the reasoning process of an argument. Viewers are now introduced with the topic of deductive and inductive arguments. A deductive argument means that there is no possibility of the conclusion being false when the premises are true. Inductive arguments mean that the premises merely make the conclusion likely (conclusion “goes beyond” the premises). Lastly inductive forms are arguments based on signs, prediction, and generalization just to name a few. Part three of the video talks about validity, strength, soundness, and......

...FUZZY MATH BUSINESS CASE Prof: Sandra Malach Student: Adam Fehr ID: 10115447 Joe Davis is a new hire and as such he has not figured out the exact inner workings of the company. With his limited experience he has already witnessed what he has thought to be a lack of ethical and accounting practices. Gallagher and MacDonald do not seem to care about their clients and are only focused on paying the lowest possible penalties to Symbol. Joe needs to decide if he should bypass both Gallagher and MacDonald and talk directly to the CEO about what he thinks is dishonest business dealings with Symbol. He has tried to get a neutral opinion by going to the company’s controller. The controller took a passive stance and was not helpful in regards to what direction Davis should take. This passive inaction made Davis question again what ethics this company has. With three of Davis’s contacts appearing to him as unethical and having poor accounting practices, Davis should talk directly to the CEO. He has already tried to bring the accounting errors to his superiors and has little success in them acknowledging the issue. Steve from Symbol has already let Davis know that there is an accounting issue. The client should not have to badger the company for its money which is owed to it. Symbol being their largest client, the utmost must be done to keep Symbol happy. Davis knows that ConnectCo owes Symbol money but is unsure how much based on ethics. By removing training days of ConnectCo’s...

...1.2.1.AK Combinational Logic Design Introduction Combinational and sequential logic are the fundamental building blocks of digital electronics. Combinational logic, which is sometimes referred to as "combinatorial logic”, is characterized by its output being a function of the current input value. A variety of different logic gates can be used to implement combinational logic circuits. Many of these gates will be studied in future units of this course. In this introductory unit, we will limit our designs to AND, OR, and INVERTER gates for the sake of simplicity. In this activity you will use the Circuit Design Software (CDS) to build and test your first combinational logic circuits. Equipment * Circuit Design Software (CDS) Procedure Now it’s time for you to implement your first AOI combinational logic circuit. The circuit that we will use for this purpose is a Car Safety Buzzer design.The design specifications are as follows: The buzzer is on whenever the door is open or when the key is in the ignition and the seat belt is not buckled. 1. Create a table that describes these design specification in terms of “highs” (1) and “lows” (0). This is when the sensor or indicator is active or not active. Seat Belt | 0 = SEAT BELT NOT BUCKLED | | 1 = SEAT BELT BUCKLED | Key | 0 = KEY NOT IN THE IGNITION | | 1 = KEY IN THE IGNITION | Door | 0 = DOOR IS NOT OPEN | | 1 = DOOR IS OPEN | Buzzer | 0 = BUZZER is OFF | | 1 = BUZZER is ON | 2.......

Fuzzy Logic Model to Determine Water Quality

...Abstract In recent years fuzzy set theory has emerged as a transcendental tool to deal with environmental engineering application having uncertainty, ambiguity and subjectivity. Analysis of surface water quality plays significant role in environmental impact assessment studies. For qualitative description of surface water quality, number of physical, chemical and biological parameters are taken into consideration, allotted a weightage factor and calculated into an index called water quality index (WQI). Water quality index uses crisp set to analyse water contaminants and hence deals with standing boundary conditions. This paper illustrates use of fuzzy inference system for analysing physical and chemical parameters to assess surface water quality. A water quality index calculated with fuzzy inference system has been developed and discussed. Introduction Determination of status of water quality of a river or any other water sources is highly indeterminate. The current method of determining water quality index which is in practice utilizes statistical approach and is not precise in most of the time. Nowadays environmental protection and water quality management has become an important issue in public policies throughout the world. Moreover, government is concerned about the quality of their environmental resources because of the complexity in water quality data sets. Many countries have introduced a scheme for river water quality monitoring and assessment,......

... Logic Application After evaluating the game of “Guess your Card”, I assume that my cards could only be 4, 5, and 9. I came up with this logic by starting with Andy. I add all three numbers together from each player. Andy has the cards of 1, 3, and 7 with a sum of 11. Belle has the cards 3, 4, and 7 with a sum of 14, and Carol has the cards 4, 6 and 8 with a sum of 18. Since each player have a different sum I took the players with the highest sum which is Belle and Carol to see which player cards would add up with my cards. Next, Belle draw the question card, “of the five odd numbers”, how many different odd numbers do you see? She answer all of them. Only because the only odd numbers she see is from Andy and Carol which are 1, 3, and 7. That's how I came up with the numbers of 5 and 9. I then, add together 5 and 9 which is 14, let's not forget in the beginning I said the sums must add up to either 14 or 18. Since 5+9=14, and the smallest card is 1 so my cards must add up to more than 14. The sum of my cards must be 18. In order for me to find out what is my final card I must subtract 18 from 9 and 5 which gives me 4. You can also see why Andy knew what cards he had. He realize that the only odd numbers Belle could see from Carol and myself were 5 and 9, but yet she claim she could see all five odd numbers. So the remaining three: 1, 3 and 7 must have come from Andy himself. That's how he figure out what he had. The logic of......
