Electric Power Steering (Abbr. EPS) is a full electric system which reduces the amount of steering effort by directly applying the output from an electric motor to the steering system and has attracted much attention for their advantages. The constitutions and working principle of EPS system was introduced. Through the control requirements in EPS system, the MAS-based EPS control strategy and architecture was discussed and the basic function and behavior of every agent was represented. And according to the different working conditions, EPS system was divided into assist control model, return-to-center control model and damping control model, and corresponding flexible PID control algorithm, Fuzzy-PID control algorithm, Bang-Bang-PID control algorithm were designed. It has practical engineering significance to the design of EPS motor control strategy, to the improvement and optimization of EPS function and to the steering manipulation safety and provides an effective control method for EPS system.
