Control Method of Valve Electric Actuator Based on Fuzzy PID Algorithm
Since the valve electric actuator has the characteristics of nonlinearity and time-varying,which makes it difficult for the traditional control method to achieve the ideal control effect,the control method of valve electric actuator based on fuzzy PID algorithm is proposed.According to the structural characteristics of the valve electric actuator,the mathematical model of the drive motor link is established as the controlled object,the fuzzy theory is added to the traditional PID controller to form the fuzzy PID control structure,the control signal is obtained by inputting the corresponding parameters,and the control signal is outputted to the controlled object to achieve the control of the valve electric actuator.The experimental results show that it takes only 0.58 s to restore the steady state after applying the abrupt signal perturbation in the process of controlling the electric actuator of the valve by the design method,which confirms that the method has strong anti-interference ability and excellent control effect.
