Abstract: A model reference adaptive controller for semi-active suspension systems in vehicle is designed on the basis of the lyapunov stability theory and the dynamics model of the quarter car. This proposed controller is composed of a tuning controller before the reference input and a state feedback controller. The adaptive control law and constrain condition are derived out. Simulation results show that the controller achieves a high robustness against non-linear and model uncertainties and disturbance

Key words: semi-active suspension, adaptive, model reference
