Control of Rack Position Actuator and Electronic Governing System in Vehicle Diesel Engine

This paper mainly studies the control part of electronic fuel injection system in diesel engine,which includes rack position control and engine speed control.For a kind of electronic actuator,this paper proposes an adaptive control method and relevant theoretic prove is conducted.Experimental results prove that this method can effectively resolve the control problem of actuator.On the base of position control system,electronic governing system was investigated.A fuzzy PID compound control algorithm is proposed.From the bench experimental results,it can be seen that the governing system has a good governing performance and anti jamming ability.
