Title Design and Implementation of Intelligent Vehicle for the
Tenth Freescale Cup—Control Algorithm Design of Visual
Guided Vehicle Under the control of lighthouse
Abstract
This paper based on the tenth "Freescale" Cup National Intelligent vehicle competition of university students,beacon Control Algorithm Design of Visual Guided Vehicle Under the control of lighthouse.In this paper, the structure and working flow of the Intelligent vehicle are introduced in detail,and the model of the vehicle is modeled by the preview tracking system.Based on this theory, the mathematical model of the rear wheel steering wheel steering gear and the rear wheel motor drive system is established.The different control strategies for different circuits are designed. The PD control algorithm of the servo system and the PI control algorithm of the motor are designed, and the simulation analysis of the control algorithm is carried out with Matlab.Finally,we debug each module respectively and the whole system.The intelligent vehicle with good performance in the course of the experiment, and it can travel smoothly on the track.
Keywords Intelligent vehicle Preview follower theory PID control Simulation model
