Abstract

Accurate engine speed control has been required to improve the shift quality of automatic transmissions. However, engine dynamics dramatically change with engine load and with the aging of the engine. Therefore, conventional controls such as PID control cause large overshoots and can not ensure accurate controllability. A control composed of a sliding-mode controller and an adaptive disturbance observer was therefore designed and applied to engine speed control. The new control had high robustness against changes in engine dynamics and excellent ability to suppress overshoot. In addition, it provided accurate and rapid engine speed control under all engine conditions.
