| Abstract: | In this paper, a quarter-car model is used to analyze dynamic performance of active suspension and skyhook damper. In view of nonlinearity of the actuator, the applications of differential geometry and accurate feedback linearization procedures to active suspension system control are investigated. A discrete time sliding mode method is adopted for the control design of the system. Simulation results of nonlinear control indicate that the ride quality of auto mobile is improved remarkably. |
