Research on Assist Characteristic of Electric Power Steering System Based on Adaptive Neuro-Fuzzy Control

The simulation model based on MATLAB/Simulink was built for the controller of electric power steering system; assist characteristic is a key part of control. The ideal assist characteristic can satisfy the requirement of steering handiness and road feel. Adaptive neuro-fuzzy control was adopted to build assist characteristic simulation controller of electric power steering system. Then the simulation test was carried out. The simulation results verify the validity of the simulation controller, which creates the research basis for preliminary ascertainment of assist characteristic and further research of control strategies.
