Abstract: A new approach for synchronous generator excitation control using fuzzy PID system with immune algorithm is presented in this paper. Firstly,this paper designs a fuzzy
self-adjustment PID controller to overcome the traditional PID control’s shortcomings those are non-liner badly and requesting precise model and so on.And then designs a new fuzzy PID controller which bases on the immune algorithm.The immunity principle is used in the fuzzy PID control which strengthens self-adjustment and adaptive ability of the control system and increases the precision and speed of the controller.
