Title Design and Implementation of Intelligent Vehicle for the Eighth 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. On the basis of mastering overall structure and principle of the electromagnetic guided vehicle, the intelligent vehicle system is modeled by using preview follower theory. The low speed and high speed dynamics model of intelligent vehicle are modeled, and steering wheel is also modeled. In order to optimize the system performance, control strategies are designed, which includes route identity strategy, motor control strategy, steering control strategy and speed control strategy. In addition, motor PID algorithm is simulated and analyzed. Finally, we debug each module respectively and the whole system, It turns out that the intelligent vehicle is stable and has excellent dynamic properties.
