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(More)
Based on dynamic model of electric power steering system(EPS), the application of mixed H2/H∞ control decides the values of the assisting torque to resolve ncertainty. Simulation results show that mixed H2/H∞ control is bette comparing with H∞ control to obtain low-frequency information from the road surface and inhibit high frequency interference, make the(More)
