摘 要:
研究带拖车移动机器人的前向路径跟踪控制和倒车路径跟踪控制问题.首先建立系统的运动学模型,并进行系统的运动特性分析;然后基于Lyapunov方法提出一种新的单体移动机器人全局路径跟踪控制器,并将其引入带拖车移动机器人的前向路径跟踪控制;再后通过运动学变换,实现了拖挂任意节拖车的系统的倒车路径跟踪控制;最后针对三车体系统的两种路径跟踪控制进行仿真,结果表明了该方法的有效性.[著者文摘]

Abstract:
The forward and backward path following control for tractor-trailer mobile robot (TTMR) are investigated. First, the kinematic model of the system pulling N trailers is established and its characteristics are analyzed. Then, by using Lyapunov method, a global path following controller for single-body mobile robot is designed and extended into the forward path following control for the TTMR. After that, based on the above controller, a novel approach to the backward path following control for the TTMR is proposed by the transformation of its kinematics. Finally, simulations for three-body TTMR are presented, and the results show the effectiveness of the approach.[著者文摘]
