中文摘要 |
针对带有执行机构饱和约束与外部干扰的轮式移动机器人, 提出了一种基于T-S模糊模型的轨迹跟踪方法.利用机器人运动特性和参考轨迹建立轨迹跟踪的误差系统并将其作T-S模型描述. 通过求解具有LMI约束的半定规划问题, 对每个线性子系统单独设计满足控制约束与H性能约束的状态反馈控制器, 并在PDC(动态平行分配补偿) 设计框架下构建全局控制器, 最后证明闭环系统的李雅普诺夫稳定性. 仿真结果验证了该方法的有效性和可行性. |
英文摘要 |
For the wheeled mobile robot(WMR) with actuator saturations and external disturbances, a tracking scheme via Takagi-Sugeno(T-S) fuzzy model is proposed. The tracking error system of WMR is established using the given trajectory and then represented by a T-S fuzzy model. Constrained H-infinity controller in the form of state feedback is also derived for each subsystem by solving LMI based semi-definite programming problems. Furthermore, the overall controller is constructed in the framework of parallel distributed compensation(PDC), and the Lyapunov stability of the closed-loop system is tested. Finally, simulation results are given and discussed to validate the proposed scheme. |
