Zusammenfassung:This paper concerns an automotive idle speed control problem. We develop an engine model for the instantaneous engine speed containing quasi-AC component. When there are different torque variations in the cylinders of the engine, the engine speed ripple fluctuates, which causes more vibration of the vehicle. We develop a control strategy to reduce this fluctuation with only engine speed as the measured variable by using 4 spark advances as control inputs.
