Abstract
In this paper a controller is derived that is capable of improving driver comfort using semi-active suspension. Model predictive control (MPC) is used to find the best possible controller for the given criterion. A fairly simple switching controller that approaches the performance of the MPC controller can be found by identifying the relation between the control signal from the MPC controller and a set of known sensor signals. The proposed controller switches on the basis of state dependent information.
