Abstract

For the purpose of fault diagnosis and tolerance, a sliding mode controller (SMC) is designed for a nonlinear full vehicle active suspension system. Since actuators are used to generate forces in active suspension, the dynamics of the four electro-hydraulic actuators are taken into consideration. Simulation is made to illustrate the proposed controller where the active suspension system performances are compared to those of passive suspension
