PID Tuning based on Genetic Algorithms in Electro-Hydraulic Position Servo System

为了改善电液伺服位置系统的控制性能,本文采用了传统遗传算法对相关PID参数进行寻优整定。通过仿真工具SIMULINK和实际试验表明,控制系统既有较快的动态响应,又有较高的稳态精度。

In order to improve the performances of electro-hydraulic position servo system,tradition GA(Genetic Algorithms)was applied to PID Tuning.The results of SIMULINK simulations indicate that the system not only has the faster dynamic response,but also shows the better ultimate precision.It was proved to be effective by test also.
