Abstract
An optimal control design for active suspension system of ground vehicle is presented. Objective of the active suspension system is to improve the vehicle performance in particularly on the ride comfort. The optimal control design is done by applying linear quadratic regulator (LQR), where the vehicle suspension is approached by a half-car model. The LQR formulates the control design problem into a optimizing problem for minimizing a quadratic cost function. Solving the optimizing problem results in an optimal states feedback control that is being applied in the active suspension system. Performance of the active suspension system is demonstrated through numerical simulations together with a passive suspension system. Evaluation of the simulation results shows an advantage of active suspension system by improving the ride comfort up to 94.81% of the passive suspension system.
