Abstract

Abstract: Based on the analysis on the mathematical model of electric power steering system，the Matalb /Simulink-based electric power steering system simulation model was established． Curvilinear assistance curve was used to emulate and PID control strategy was adopted for the closed-loop tracking control of the objective current in the motor． The analysis results confirmed that: the proposed PID control strategy is of good boost．

Key words: electric power steering, curvilinear assistance curve, PID Control, simulation, modeling
