The automobile is composed of too many systems. One of systems is the suspension system. The main functions of the automotive suspension system are to provide vehicle support, nstability and directional control during handling maneuvers and to provide effective isolation from road disturbances. The suspension system has to balance the trade off between ride comfort and handling performance.This paper analyses the passive suspension system and active suspension system using Linear Quadratic Regulator (LQR) controller. A linear quarter car model is used for the analysis and simulation. The performance of the LQR controller is compared with the passive suspension system. The simulation results show that LQR controller improves vehicle ride comfort.

Abstract


The automobile is composed of too many systems. One of systems is the suspension system. The main functions of the automotive suspension system are to provide vehicle support, nstability and directional control during handling maneuvers and to provide effective isolation from road disturbances. The suspension system has to balance the trade off between ride comfort and handling performance.This paper analyses the passive suspension system and active suspension system using Linear Quadratic Regulator (LQR) controller. A linear quarter car model is used for the analysis and simulation. The performance of the LQR controller is compared with the passive suspension system. The simulation results show that LQR controller improves vehicle ride comfort.
