PID控制器参数的遗传算法优化设计

Optimized design of PID controller using penetic algorithms

提出一种交流伺服系统速度控制器的设计方法，即将控制器设计问题作为一参数优化问题，采用遗传算法对ＰＩＤ控制器参数进行优化．仿真实验结果表明，利用此方法设计出的速度控制器具有优良的伺服性能．

A design method of sped controller of AC servo system is proposed in this paper. The parameters of PID controller is optimized by genetic algorithms.The simulation result shows that the speed controller designed by this method is of better servo performance than that by traditional method.
