Many researchers have published many related papers concerned suspension systems in recent years. This paper derives a bilinear model for a quarter car suspension system and designs a regulator to reduce the vehicle vibration by using Lyapunov theorem for semi-active, active, and combined suspension systems. The paper considers passive, semi-active, and active suspension systems. Their effectiveness will be compared via the computer simulations and find the optimal gain of the suspension system. This paper also considers the active suspension system by using LQR (Linear Quadratic Regulator) control law.
