Abstract

This paper presents an adaptive gain scheduling control strategy for vehicle suspension design. A quarter car suspension model with a nonlinear dynamic model of the hydraulic actuator is employed. The feedback control gains of the controller designed using a combination of LQR control and nonlinear backstepping techniques are adapted to the changes of road input in order to provide optimal suspension performance in different conditions. Simulations show that the control strategy is feasible and effective
