| Abstract: | In order to accelerate the ESP system response time,improve the stability of the vehicle,this paper adopts fuzzy control theory to make feedback control of the ESP system.Four wheels vehicle model with eight degrees of freedom and Gim tire model are established,and in the good flexibility,robustness of fuzzy PID controller is introduced based on the ant colony algorithm,the design based on ant colony optimization of fuzzy PID control system structure and its calculation method,so as to achieve parameters optimization design,then a simulation model generated by Simulink software is used.Simulation experiment proves that this method can accelerate the speed of convergence system and shorten the system response time. |
