The aim of this paper is to design a linear quadratic regulator (LQR) for a vehicle suspension (VS) system to improve the ride comfort by absorbing the shocks due to a rough and uneven road. For designing of the LQR, a fourth-order linearized model of the VS system is considered. The LQR is a novel approach whose gains dynamically vary with respect to the error signal. The validation of the improved control performance of LQR is established by comparative result investigation with other published control algorithms. The comparative results clearly reveal the better response of the suggested approach to control the oscillation of the VS system within a stable range with respect to the accuracy, robustness, and capability to control uncertainties.
