摘要
该文提出了基于遗传算法的PID控制器参数优化方法,该方法只需给出大概的PID参数范围即可得到控制性能最优的PID参数。仿真结果表明:当被控对象存在较大纯滞后时间常数特性时,采用本方法优化PID控制器参数可获得比较满意的调节效果。
We develop a method based on genetic algorithms to solve PID controller parameters optimization. By using the method only given the approximate ranges of the PID parameters, we can get the PID parameters for the optimal control performance. The simulated result shows that the step-respond of PID controller parameters tuned by this method is satisfied when the controlled object contains a bigger time delay and large time constant characteristics.
