Abstract

Aiming at the nonlinear

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.
