Modeling and Simulation of Slip Frequency Control for Induction Motor in Electric Vehicle EHPS System

Abstract:

According to the assist characteristic of induction motor in Electro Hydraulic Power Steering (EHPS), a slip frequency control system for EHPS system in electric vehicle applied to Electric Control Units (ECU) has been proposed. We analyzed induction motor operating characteristic in EHPS and established a model, and simulated based on Matlab/Simulink. The simulation shows that the proposed control strategy can obtain good control effects, the proposed algorithm is verified.
