By analyzing an electrical power steering system (EPS) structure and its dynamical characteristics, this paper presents an improved PD control method based on double fuzzy sets and auto-tuning techniques. In order to overcome the conflict between steering portability and sensitiveness and obtain ideal EPS assist steering characteristics, the PD parameters should be adjusted online in different circumstances and ideal PD parameters can be acquired. The simulations of the improved PD controller and the conventional one were carried out. The results show that the improved PD controller is more effective and robust than the conventional PD one.
