A new electric actuator based on STC89C52RC was designed and the model of the driving system was built. In the controller ,a strategy of fuzzy PID control based on self-tuning parameters was adopted so that the opening of the valve could be adjusted accurately. The MATLAB simulation results show that the designed controller has quick and smooth response and the dynamic property of the system is improved by comparison with original PID controller.
