Optimal design and simulation of EPS parameter based on matlab/simulink

To raise the handiness and agility of vehicles’steering,a method which combines simplicity shape algorithm with fuzzy PID control method,is brought forward to design EPS controller.This method provides theoretical basis for optimizing the design of the controller.Then we build the EPS math model and design fuzzy control rules of regulating controller’s parameters.The system model is buitlt with optimization toolbox in MatLab and the simulation experiment studies are carried out in Simulink.The results of simulation experiment confirm that this method can enormously improve the time domain performance evaluation,and improve handiness and agility of vehicles’steerer.
