According to the return-to-center characteristics of a steering system and the deficiencies of an electric steering system model in the process of return-to-center, a new return-to-center control scheme was put forward. By dint of an expert controller, a control scheme that can convert in different steering state was realized. Based on above analysis, a new pattern of test-bed was designed, which could simulate the process of steering better. The results show that this control scheme can obtain excellent return-to-center performance and improve the stability of steering system.
