Electric Power Steering System

The first of all, the multidisciplinary modeling and analyzing for the electric power steering system (EPS) is made. The design method based on the model is proposed and the EPS control system is analyzed. On the basis of deeply observing and studying S/T singular value curves, a robust control algorithm of back-calculation is put forward. After analyzing the deficiency in the single-loop control structure of the EPS, the dual-loop control structure of the EPS is developed. The inner loop controller is designed using the single neuron PID algorithm, and the new robust control algorithm is proposed to design the outer loop controller. The simulation results in the frequency-domain S/T curves of the EPS system and the hand force step input of the steering wheel show that the designed controller is simple and effective, and has good robust stability and robust performance.

Electric Power Steering System

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 PID controller.
