| Abstract: | A speed identification method based on recursive least square(RLS) algorithm is introduced into electric power steering(EPS) system for estimating the speed of EPS motor.By using the estimated motor speed,combined with vehicle speed,the corresponding damping characteristics are designed,the damping control strategy is proposed and the simulations on motor speed identification and damping characteristics are performed.The results show that the speed identification with RLS algorithm has low cost and high rel... |
