Sliding Mode Variable Structure Control for Electric Power Steering System

摘要：

　　There are many uncertain factors because of the nonlinearity of system and the road surface interference in the electric power steering system (EPS),and a PID controller is only used suitably when the system is a linear system and the system parameters are certain.A sliding mode variable structure controller which is based on the exponential approach law is proposed for EPS for the nonlinear system and the road surface disturbance.Simulation shows that the proposed controller has the steady performance and the dynamic performance,and its sliding mode is absolutely self-adaptive,so the sliding mode controller can be used to robust control for electric power steering system.
