Fuzzy-PID dual mode fuzzy control of the electro-hydraulic deviation control system

Deviation for a practical electro-hydraulic deviation control system, mathematical model is set up. Fuzzy control is introduced on the basis of PID control and FUZZY-PID dual-mode fuzzy controller is designed. PID and fuzzy control can be switch by setting the error value. Simulation results show that the system retains the respective advantages of the two controllers, and control performance is greatly improved.
