Control of linear full vehicle active suspension system using Sliding Mode techniques

For the purpose of fault diagnosis and accommodation, a Sliding Mode Controller (SMC) is designed for a linear full vehicle active suspension system. An investigation about the available sensors for the controller implementation is also presented. Two levels are studied: the level of vehicle prototypes and the level of industrial vehicles. Difficulties of vehicle instrumentation and possible solutions are discussed. Simulation is made to illustrate the proposed controller where the active suspension system performances are compared with those of passive suspension.
