A Comparative Study Between PID and Fuzzy Controller

Students earlier were reluctant to adopt smart techniques for controlling for various reasons like stabilizing properties and characteristics of performance could not be verified, analytical comparison of its advantages/disadvantages over other conventional methods were not known and moreover the approaches were not widely used by working engineers. Whereas newer intelligent control technologies like fuzzy, neural and hybrid controls are being adopted now-a-days. Fuzzy logic is an effective controller tool where variable relationships can be represented in logical form. Fuzzy logic quantifies the linguistic variable terms so that they can be described as continuous values and allows mathematical equations to represent the system characteristics and responses. In process or manufacturing industries like PI or PID techniques of control, are widely adopted due to their simple method, their easy operation, and its tuning techniques are easy to understand.
