time-varying and pure hysteresis problems of the intelligent pneumatic valve control system
an approximate mathematical model is established based on the physical characteristics of the system terminal control part. On the basis of amalyzing on traditional proportional-integral-differential( PID) and fuzzy PID algorithm cannot solve the automatic online tuning and hysteresis problem
an improved gray predictive fuzzy PID controller is designed. The controller combines the improved gray prediction module and the fuzzy PID control module to realize the advanced control and fuzzification of the system. The simulation results show that the proposed improved gray prediction fuzzy PID algorithm has the advantages of fast response
small overshoot and strong anti-interference ability. Its regulation performance is better than traditional PID and fuzzy PID algorithm in the application of intelligent pneumatic valve system.
