摘要：
Assistance control is an important control model of electric power steering system. When designing assistance control algorithm, we should not only consider the handiness and stability of steering, but also think of the assistance stability and disturbance resistance from the road surface. In order to improve the overall performance of electric power steering, robust control theory is applied to develop the assistance control algorithm. Based on the above, a robust controller was designed. The influences of the assistance torque deviation and the road surface disturbance on steering were selected as the controlled output. Then the designed controller was tested on electric power steering test bed. The test results show that the robust controller is of better assistant performance than traditional PD controller.
