This article establishes a mathematical model for the flow control system of a single screw dispensing valve pump,adopts a fuzzy PID controller to improve system control performance,and determines the domain variable range,language value,membership function,and fuzzy control rule table of deviation e,deviation change ec,output Kp,Ki,Kd based on the actual sys-tem and Mamdani fuzzy inference algorithm.A fuzzy PID controller is constructed.Using MATLAB/Simulink software to conduct simulation experiments on the constructed system controller,and by comparing the step response diagrams of traditional PID control and fuzzy PID control,it is found that the fuzzy PID controller has the best effect,and has the advantages of fast adjustment time,small overshoot,and strong anti-interference,which,to some extent,improves the stability of the single screw pump flow control system.
