| Abstract: | Stability and disturbance resistance are important performance indices of electric power steering system. The vibration of steering wheel caused by unstable electric power steering system and extra input disturbance have direct influence on the steerability of an automobile. The electric power steering system stability is studied in this paper, and the influence of road disturbance and sensor noise is analysed. H-infinity control theory with classical PD control method is applied to the design of the control system, and a controller is designed. The computer simulation results prove that the electric power steering control system designed has a good stability, and can attenuate the influence of high frequency road disturbance and torque sensor noise. |
