In this paper, the measured output feedback design control strategies , automotive electric power steering system (EPS) and integrated control of active suspension system (ASS) . First, simulation studies have been carried out on the 1 / 4 car the steering situation Suspension system motion characteristics : Next, establish vehicle steering and suspension integrated model , a LQG control strategy is designed to improve the body yaw rate response , the vertical acceleration of the body and the car body side angle output ; once again , adding the car EPS system , the establishment of a comprehensive model of EPS and ASS , a random sub-optimal output feedback control strategy is designed to improve the portability steering , handling and stability , ride and safety ; then the optimal output feedback sliding mode variable structure control strategy , EPS and ASS integrated control system design and simulation results show that the design of an integrated control strategy can not only improve manipulation of light and can be used to suppress the body posture changes : Finally, the details of the process of the integrated controller microcontroller hardware circuit design and software program , and a variety of operating conditions on the road test , the test results prove that the design integration the effectiveness and feasibility of the controller .
