| 摘 要： | 提出一种基于局部T-S模型不确定切换系统的可靠控制方法，将输入空间划分为若干个区域，在每一区域内构建局部T-S模型并设计相应的控制器；这样由于模糊论域的变小而提高了逼近精度，然后再通过多模型切换控制，实现对整体非线性系统的逼近与控制．在此，利用并行分布补偿技术（PDC），借助于LMI和凸优化方法，得出系统鲁棒凡可靠控制器的解析式．

| Abstract: | An uncertain switching reliable control method was proposed for nonlinear systems based on local T-S models, which divides the input space into multiple regions with T-S models and controls in every region. This method improves precision as the fuzzy domain decreases. The approach and control of this nonlinear system is established by the multiple-model switching control. Based on the technique of parallel distributed compensator （PDC）, a robust H∞ reliable controller ensuring the closed-loop system to be regionally stable is designed by means of the linear matrix inequality and convex optimization technique. |
