Based on genetic algorithms, an online optimizing method for PID paramenters of valve-controlled motor speed governing system was presented. The difficulty in PID parameter adjusting was reduced and the control precision of the system was improved using the global search capability of genetic algorithm. The experimental results and optimization calculation implemented on Matlab platform show that the designed PID controller has high robustness. The control system shows a very good dynamic quality and stable precision.
