In this thesis, new methods for the realization of linear quadratic optimal semi-active suspension control in a real vehicle are presented, resulting from the requirement of the concept to be suitable for series production. For the implementation, a new observer concept is presented, which guarantees reliable estimates in realistic test conditions. The control method is selected based on a methodological comparison. In order to insure the suitability for series production the influence of parameter variations is investigated, a soft switching controller structure for adjusting the controller parametrization is proposed and the the concept is extended to driving state adaptive control. The experimental validation shows, that ride comfort and ride safety can be significantly improved compared to the well-established Skyhook control.
