Fuzzy logic is a very powerful and direct technique for problem solving, which has recently acquired a wide circulation, especially in areas of control and decision making.Has emerged as a tool to control subsystem and complex industrial processes, as well as for entertainment and home electronics, diagnostic systems and other expert systems.Traditionally the logical premises are just two extremes: either they are completely true or totally false. In the world of fuzzy logic, logical assumptions to change in a degree of truth range from 0 to 100 percent, this allows the mathematical approach to vague language of the common man as it is full of vague terms like "slightly" "a lot", "warm", etc.Seeing this, the paradigm of "is" and "not" is a serious limitation in building control systems real time process control and expert systems. Many expert systems have the ability to make decisions based on vague or inaccurate entries. This ability is very difficult or impossible to obtain using conventional logic, being in these areas where fuzzy logic comes.
