Fuzzy Systems

• Fuzzy logic is a form of many-valued logic in which the truth values of variables may be any real number between 0 and 1 inclusive. 

• It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false.By contrast, in Boolean logic, the truth values of variables may only be the integer values 0 or 1.

• Fuzzy Logic System was invented by Lotfi Zadeh. Also, he observed, unlike other computers, it includes a range of possibilities between YES and NO, in a human decision.

• Can be implemented in systems with various sizes and capabilities. That should be range from mall micro-controllers to large. Also, it can be implemented in hardware, software, or a combination of both in artificial intelligence.

• Meaning of the expressions cold, warm, and hot are represented by functions mapping a temperature scale. A point on that scale has three "truth values"—one for each of the three functions. 

• The vertical line in the image represents a particular temperature that the three arrows gauge. Since the red arrow points to zero, this temperature may be interpreted as "not hot". The orange arrow (pointing at 0.2) may describe it as "slightly warm" and the blue arrow (pointing at 0.8) "fairly cold".

           

          Fuzzy Systems Applications:

• Automotive Systems
• Consumer Electronic Goods
• Domestic Goods
• Environment Control

        

          Advantages of Fuzzy Systems:

• Generally, in this system, we can take imprecise, distorted, noisy input information.
• Also, these logics are easy to construct and understand.
• Basically, it’s solution to complex problems. Such as medicine.
• Also, we can relate math in concept within fuzzy logic. Also, these concepts are very simple.
• Due to the flexibility of fuzzy logic, we can add and delete rules in FLS system.
