Sliding mode based control strategies for automotive systems

A variable structure control system (VSCS) may be used to provide robust control of uncertain, often nonlinear, dynamical systems which are subject to external disturbances. The method has thus received some attention from sections of the automotive industry where nonlinear behaviour is common, the operating environment is harsh and tight performance specifications are often required. This paper first outlines the fundamental properties of the VSCS philosophy. The development of a simple VSCS for an automotive actuator including the results of bench test trials is reviewed. The conclusion offers an analytical overview of the best contemporary theoretical practices in relation to the needs of the automotive industry.<
