Rapid Engine Speed Control for AMT Using Two-Degree-of-Freedom Sliding Mode Algorithm 2005-01-1592

An accurate and rapid engine speed control has been required to improve the shift quality of automated manual transmissions. However, conventional controls could not provide sufficient controllability. They caused the overshoot and steady-state error of engine speed from target values. Therefore, a two-degree-of-freedom sliding mode algorithm was newly designed and applied to the engine speed control. This algorithm can independently assign the disturbance suppression characteristic and tracking performance, and has excellent robustness against the changes in engine dynamics. As a result, the overshoot and steady-state error were prevented under all engine conditions.
