Research on Fuzzy PID Gate Flow Control System Based on Grey Prediction
In order to solve the problems of large inertia,time-varying nonlinearity and pure hysteresis in the gate flow control system,a fuzzy PID gate flow control system based on grey prediction is designed.The grey prediction fuzzy PID control algorithm combines the advantages of fuzzy PID algorithm and grey prediction algorithm.The grey prediction algorithm is applied to the feedback channel of the fuzzy PID control system to predict the next output of the gate control system,so that the flow control of the gate can be adjusted in advance.Through MATLAB software simulation,the results show that compared with the traditional PID control algorithm and fuzzy PID control algorithm,the grey prediction fuzzy PID control algorithm can effectively overcome the adverse effects of time delay,parameter time-varying and other factors on the system,and has a better control effect on the flow control of the gate.
