MIMO CONTROL OF AN IC ENGINE USING DYNAMIC SLIDING MODES

摘要

The three stage mean value engine model (MVEM) of an IC engine is first represented in Local Generalized Controller Canonical Form (LGCCF) and then dynamic sliding mode control has been employed to effect speed and manifold pressure trajectory tracking. The approach produces a dynamical discontinuous feedback which results in a chatter free response. The particular choice of sliding surface is input dependent. Air-fuel ratio is stabilized to its ideal sto-ichiometric value by using an appropriate sliding surface.
