According to the assist characteristic of AC asynchronous motor in electro hydraulic power steering (EHPS ),and electric control uints(ECU),a slip frequency controll system for EHPS System in electric vehicle has been proposed and simulated based on Matlab/Simulink. The simulation results show that the proposed control strategy can obtain good control effects,the effetiveness of proposed algorithm is verified.
