Abstract: The pressure supply system of the atomizing nozzle,being characterized by nonlinear and time-varying,is rather difficult to be described by the accurate mathematical model.Effective control of the system is hard to realize by using normal PID or fuzzy control alone.In this paper,an approach of fuzzy-PID hybrid control is presented by utilizing the advantages of both normal fuzzy and PID controller for the purpose of improving the dynamic and steady state performance of the control system.Thus,the control of the pressure supply system of the atomizing nozzle is executed in such a way that in the region further away form the working point,it mainly depends on fuzzy control,and near the working point,it mainly depends on PID control.The simulation and experiment show that the hybrid controller is able to control the supplying pressure at the preset value efficiently.It features quick response,high steady state accuracy and perfect steady robust performance.
