摘要
Abstract
Because the return ability of the electric power steering (EPS) system of a steering wheel is excessive at its high speed but insufficient at its low speed,a new return-to-center control strategy for controlling its speed was put forward.Firstly,the dynamics model of the R-EPS system was built.Then the method for obtaining return curves was introduced.Finally,the control strategy was simulated with Adams/Simulink.Compared with the fuzzy PID control strategy based on the conventional angle of the steering wheel,our control strategy based on the angular velocity of the steering wheel is innovative.The simulation results show that our control strategy gains a better return ability than the conventional control strategy and that the return is faster and more accurate.关键词
