For the problem of poor control precision of high-speed solenoid valves which are widely used in aero-engine control systems, a fuzzy-PID control system based on Soc single-chip is designed in this paper by using fuzzy self-tuning of PID parameters control algorithm. Because the Soc single-chip can control the output flow of high-speed solenoid valve very well by its PWM function, the monitoring system may not only enhance the control precision of high-speed solenoid valve, but also may improve the anti-interference performance greatly. Moreover, Simulation results show the effectiveness of the proposed method.
