Semi-active truck suspensions to improve road-friendliness have been developed and implemented, and demonstrate the capability of such control systems to reduce the road-tyre forces by about 10-30 %, without adverse effects on ride comfort. This corresponds to a reduction of road damage up to 70 % or to a possible payload increase by 1 ton for 10 tons of original payload. From the point of view of the control design methodology, a new, rather general, strategy for the analysis and design of semi-active control has been developed and tested. Its main steps are to develop a control law based on physical insight into the plant, to determine the parameters by a multi-objective parameter optimization (MOPO) approach using representative excitations with possibly state-dependent gains in the case of highly nonlinear plants, and to verify the results on a full nonlinear simulation model if simplified design models are being used.
