Abstract

A flatness-based end controller of an automotive solenoid valve has been demonstrated in both simulation and on an actuator test-bench. The simulation model provides an accurate representation of the real system and allows for the development of control strategies. The simulation results are contrasted with those of an actuator test-bench equipped with 42 volt automotive solenoid valves and a pressure chamber to simulate valve opening with exhaust gas pressures. A flux-based sensor which is suitable for real engine operation is used for position estimation in the soft-landing control
