Implementation of Three Phase Induction Motor Control Drive Using PID and FUZZY Technique and Their Comparison

The induction motors were characterized by complex,highly nonlinear and time varying dynamics,and hence their speed control is a challenging problem in the industry.the advent of vector control problems the development of any for the such design of such control systems undoubtedly requires the synthesis of many concepts from artificial intelligence.the most commonly used controller in the industry field is the Proportional plus-integral-plus derivative(PID) controller.fuzzy logic controller(FLC) provides an alternative to PID controller,especially when the availble system models are inexact or unavailble.However it further needs to be improved in terms of overshoot and setting time.So control strategies based on soft computing could be good alternative.This paper describes the implementation of controllers based on PID and fuzzy logic strategies.A comparative performance analysis demonstrates that the clever exploring of fuzzy logic control strategies circumvents the demerits of PID control strategies.
