MPC Application in Trajectory Tracking 🤖

简介 📖

本项目基于 ROS navigation + MPC 实现。navigation完成感知,全局规划,定位等任务,MPC订阅全局路径并进行跟随。项目使用的MPC是基于麦轮底盘运动学模型的线性MPC(三积分模型),对麦轮的速度,加速度,加加速度进行了约束。仿真环境使用的是 GAZEBO,地图为科大讯飞17届智能车线下赛地图,仿真车模使用的是16届科大讯飞智能车竞赛线上赛车模。MPC基于高飞老师运动规划课程的作业修改。

不足 😕

严格来说,MPC跟随的是 path 而不是 Trajectory 。因为MPC直接跟随的navigation输出的全局路径,这个路径只有位置信息,也就是说这个路径是无运动学约束的!想要达到更好的效果应该对其进行运动学插值,使其具有速度,加速度,加加速度信息。

NOTE 🔑

项目中只包含MPC部分,需要自己修改 部分关话题名称进行功能移植
