Model and H/sub /spl infin// robust control design for electric -power steering system

In this paper, aimed at nonlinear MIMO EPS system, the robust control method was used to design controller. Based on the uncertainty analysis of EPS system, the state space matrixes were determined and extended to general controlled object. The H_ method was introduced to minimize the effect of disturbances on outputs. The detailed design of controller was given add the simulation results justified that the robust controller improved the performance of EPS.
