GA-based fuzzy-PID excitation controller for synchronous generators

Based on the general fuzzy-PID(Proportional,Integral and Differential) excitation controllers,an excitation controller for synchronous generators is brought forward,whose quotation factors and scale factors are optimized by GA(Genetic Algorithm). The automatic excitation system is introdu-ced,as well as the principle,architecture and functions of the fuzzy-PID controller. The imple-mentation of optimization using GA is presented. Simulations are carried out and the results show that the excitation controller designed has better dynamic and static performances.
