Study on Control Strategy for Electric Power Steering System

According to the power-assisted request of steering system,some research on EPS control scheme has been done.The PID control method which is based on fuzzy auto-turning technique and nerve-net are combined to realize assisting control.Based on analyse above,a new test-bed was designed.It can simulate the pocess of steering better.The results show that this control scheme can lighten steering torque and restrain disturbing signals which come from tyre,at the same time,the stability of steering system is improved.
