In this paper an analysis is performed on a quarter-car model of car suspension, with semi-active and active damper, utilizing sliding mode (SMC) and linear-quadratic control (LQR). The effect of control parameters and time delays in the transmission of control signal on the factors related to the safety and comfort of driving, is investigated. The results obtained from numerical simulations are shown in the form of frequency characteristics for several selected performance factors.
