| 摘要: |
| 针对麦克纳姆全向轮驱动的移动机器人轨迹跟踪控制问题，设计了一种自适应滑模控制器。将自适应鲁棒控制应用于麦克纳姆轮驱动的移动机器人轨迹跟踪以获得良好的动态跟踪性能以及鲁棒性能。首先对基于麦克纳姆轮的移动机器人进行了运动学建模，在此基础上进行了自适应鲁棒控制器设计。提出了一种比例-积分-微分（PID）形式的滑模面，满足了系统的鲁棒性要求；设计了一种能够快速收敛的趋近律，减少了整定参数所消耗的时间并能有效抵抗外部扰动。最后，存在脉冲扰动以及正弦信号扰动条件下对控制器进行了仿真验证，证明了所提控制器的优越性，通过轨迹跟踪控制的样机试验，证明了该方法的实用性和可靠性。 |

| Abstract: |
| An adaptive sliding mode controller was designed for a mobile robot driven by four mecanum wheels. The original contribution of this paper is employing adaptive robust controller to mecanum wheels driven mobile robot for obtaining better tracking and robustness performance. To complete the design of the controller, the kinematic model of the mobile robot driven by mecanum wheels was firstly proposed. An adaptive robust controller was designed subsequently. A sliding surface was designed in Proportional-Differential-Integral form,which satisfied the robustness requirements of the system. Besides, a reaching law which has quick convergence was introduced, which reduced the time consumed by the setting parameters and resisting external disturbance. The controller was demonstrated in the presence of impulsive disturbance and sinusoidal signal disturbance, which proved the superiority of the proposed controller. Finally, an experimental verification of trajectory tracking was implemented to verify the practicability and effectiveness. |
