Presented in this paper is a pointwise optimization approach for synthesizing semi-active vehicle suspensions. In particular, the control algorithm is obtained by optimizing a performance index pointwise in time. The resulting control law has a state feedback structure suitable for real time implementation and is a hybrid control scheme combining a simple one-step ahead minimization and an optimal-aiming strategy specifically chosen for increased ride comfort while satisfying constraints on road traction and rattle space. Simulations with a quarter car model confirm the efficacy of the proposed approach.
