An approach for the implementation of Intelligent PID controller based on Fast Genetic Algorithm

摘要

An efficient controller named Intelligent PID is proposed based on hybridization between original PID tuning methods and fast genetic algorithm (FGA) to enhance the transient response of automatic voltage regulator (AVR) in synchronous machine. PID controller has several advantages compared with another controller, but it's susceptible to the local minima problem and does not give sufficient output response. Therefore, FGA is used here to overcome this problem and to enhance the output response. The performance of the proposed controller is tested and compared with the original PID controller. The results demonstrate that, the intelligent PID is an effective controller to enhance the transient voltage response of AVR system.
