Abstract
This paper presents a novel control method for torque generation in spark ignition (SI) engine. A model-based approach is employed to control engine torque output by adjusting throttle air intake with considerations of robust stability and performance. Discrete event engine model (DEM) is adopted with an addition of torque generation dynamics. Disturbance observer (DOB) techniques are utilized to achieve robust stability and performance by regarding the discrepancy between the actual plant and the nominal plant with desired plant characteristics as an equivalent disturbance input, which is estimated and cancelled. The desired plant behavior is stably realized by the DOB up to a bandwidth sufficient for a torque control application covered in our previous works. Numerical results show the effectiveness of the proposed scheme.
