| 摘 要： | 研究了一类可以平滑切换时刻输出跳变的多模型切换控制器的设计问题,基于T-S模糊模型提出一种非线性系统模糊平滑切换多模型控制,将输入空间划分为若干个模糊区域,使区域边界模糊化,在每一区域内设计局部T-S模型和控制器,从而使控制器切换在模糊了的边界处进行,保证了切换过程中系统状态轨迹的平滑性.仿真结果证明了方法的有效性.

| Abstract: | To solve the problems in designing a switching controller for smoothing chattering at the time of switching in multi-model systems, a fuzzy smooth switching multi-model control for nonlinear systems is proposed based on T-S models. The proposed strategy can divide the input space into multiple fuzzy regions to blur the boundaries and can facilitate the design of local T-S models and controllers in each region, which guarantees the smoothness of the system state trajectory in the process of switching controllers on the blurred boundaries. The effectiveness of the proposed method is demonstrated by simulation results. |
