Design of Vehicle Rack Position Actuator and Electronic Governing System

This paper mainly studies the control part of electronic fuel injection system in diesel engine, which includes rack position control and engine speed control. An 80C196KC single chip is used in the control system. The drive circuit of the electromagnetic actuator and the double feedback circuit of the rack position are designed, and the examination and calculation of the speed are given. This paper proposes a robust adaptive control algorithm to electronic actuator. A fuzzy-PID compound control algorithm is proposed because the model of the diesel engine is very complex. Simulation and experiments are given in the end.
