摘要
针对T-S模糊系统,研究了非脆弱H∞跟踪控制器的设计问题。目的是通过设计跟踪控制器使得被控闭环系统满足给定的H∞跟踪控制性能指标。本文采用线性矩阵不等式(LMI)方法,求解过程不必通过二次迭代的两步算法,所设计的控制器在一定的加性参数变化情况下,仍能保证系统的渐进稳定性。最后,通过单关节刚性机械臂系统的仿真实验表明了该方法的有效性。
According to the T-S fuzzy systems, a non-fragile H∞ tracking controller is designed in this thesis. The closed-loop control system can meet H∞ tracking performance via the tracking controller that to be designed. The sufficient conditions of controller are obtained via linear matrix inequality （LMI） method. The process of solve without use a two-step iterative algorithm. The designed tracking controller can still ensure the systems are asymptotic stability with some controller parameter perturbations. Finally, the simulation experiment of single-link rigid robot shows the validity of the proposed method.
