摘要: 针对轮式移动机器人(Wheeled Mobile Robot-WMR)自身欠驱动的特点,并考虑到实际工作时的各种约束和限制,提出了一种基于模型预测控制(Model Predictive Control -MPC)的多约束轨迹规划方法。可以对车体自身的运动学约束、物理约束以及避障等约束进行集中有效的处理,可以生成符合车体自身模型特点并满足各种约束的可行轨迹,充分保证了轮式移动机器人自主行驶的可行性,安全性,高效性。仿真结果充分验证了该方法的有效性。

Abstract: Aiming at the underactuation of the Wheeled Mobile Robot (WMR) and considering the various limitations and constraints during the actual operation, a trajectory planning method based on the Model Predictive Control (MPC) is proposed.This method can deal with the kinematics constraints, physical constraints and obstacle avoidance constraints unifiedly and effectively. It can generate the feasible trajectories that conform to the characteristics of the car body model and satisfy the various constraints. It fully guarantees the feasibility, safety and efficiency of the autonomous driving of wheeled mobile robots. The simulation results fully verify the effectiveness of the proposed method.

Key words: trajectory planning, multiple constraints, wheeled mobile robot, model predictive control
