LQR Anti-rollover Control of Active Suspension in Vehicle

Abstract

In order to improve the ability of anti-rollover for vehicle, the paper established a 4 DOF vehicle rollover dynamics model, and proposed a LQR control strategy based on active suspensions for vehicle. Under the Matlab/Simulink, the simulations and the results show that the presented control scheme not only can reduce the roll angle and roll angular velocity, but also can improve the rollover stability of the vehicle, and reduce the possibility of vehicle rollover accident.
