Title Design and Implementation of Intelligent Vehicle for the Ninth Freescale Cup—Control Algorithm Design of Electromagnetic Guided Vehicle Control System
Abstract
Based on the Freescale Cup, the control algorithm of electromagnetic guided vehicle is designed. First, the structure and working principle of electromagnetic guided vehicle are introduced in the paper. Then，the intelligent vehicle system is modeled by using preview follower theory. On the base of mastering overall theory, the front steering wheel is modeled and the rear driving wheel is also modeled. The design of rear driving wheel algorithm with closed-loop PID is completed. The design of front steering wheel algorithm is also completed, which adopts fuzzy control. Next, the article completes the simulation analysis to the algorithm which is mentioned above. Finally, we debug each module respectively and the whole system, It turns out that the intelligent vehicle is stable and has excellent dynamic properties.
