摘　　要：针对同步发电机励磁系统提出一种新的参数自校正的PID控制器,采用极点配置的设计方法,通过在线辨识同步发电机的参数,实时改变PID控制器的增益系数,从而实现同步发电机励磁的自适应最优控制。仿真结果表明该方法十分有效。A new self-tuning PID controller for the synchronous generator excitation system is proposed. The adaptive optimal control of synchronous generator excitation is realized in this system, which is based on the approach of poles assigment, on-line identification of the parameters of the synchronous generator, and real-time alteration of the gain coefficients of the PID controller. The simulation result shows that the approach is very effective.
