A Fuzzy Control in Electric Power Steering System

In this paper, the constituent of the electric power steering (EPS) system and its operational mechanism are introduced, Contrast tradition PID control and the limitation of the PID control, the feasibility applying fuzzy control on EPS system and the comparative advantages are analyzed in detail, on the base of which a primary fuzzy model of EPS system is presented. Finally has produced in the EPS project fuzzy control concrete realization. The practice result indicated, Uses the fuzzy control in the electric power steering control system to be allowed enable the system to have a stronger robustness. In the enhancement steering system operation smart simultaneously guaranteed the pilot can obtain the full road feeling, thus obtains ideally boosts the characteristic.
