Improvement of Torque Control in EPS Using Induction Motor

Abstract:

In order to solve the torque control problem in electric power steering using induction motor,the system mathematical model was established and the impact on the torque control caused by the variation of rotor resistance was analyzed. Using feed-forward and feedback integrating control and on-line resistance identification to improve the accuracy of torque control and current tracking response. Simulation comparisons showed that the proposed method could significantly improve the current response speed and accuracy in induction motor control of electric power steering system.
