Electric Power Steering System

Based on the interference characteristics of the active suspension anti-rollover control system and electric power steering system, combining vehicle active suspension anti-rollover control system model, electric power steering system model and the steering model, the automobile system dynamic model was established. The optimal control strategy of LQR(linear quadratic regulator) was designed, and integrated control system of the anti-rollover control system and electric power steering was realized. Under Matlab/Simulink, the simulation was done and the results show that the presented control scheme can improve handiness of electric power steering system, and has a good anti-roll and anti-pitch ability.
