Handling performance for active rear-wheel steering vehicle robust control

The vehicles always undertake different loadings and variation road friction coefficient including external disturbances and the design of vehicle control system has model errors in fact, the primary design techniques for active rear wheel steering vehicle controller are their inability to degrade the performance of closed-loop systems. The design of yaw rate tracking control system architecture by using robust control is presented and the weighting functions are selected. The results show that the control system has fine dynamic characteristic, robust stability and robust performance, and the active rear steering vehicle with the proposed control strategy can provide greater maneuverability and driving safety.
