Abstract

In this paper, the design of a two-level controller is proposed for active suspension systems. The required control force is computed by applying a high-level controller, which is designed using a Linear Parameter Varying (LPV) method. The suspension structure contains nonlinear dynamics of the dampers and the springs. The model is augmented with weighting functions specified by the performance demands and the uncertainty assumptions. The actuator generating the necessary control force is a highly nonlinear system, for which a low-level backstepping-based force-tracking controller is designed. The operation of the two-level controller is illustrated through simulation examples.
