摘要： 提出一种基于局部T-S模型的非线性系统多模型切换控制，将输入空间划分为若干个区域，在每一区域内设计局部T-S模型和控制器，这样在模糊规则数相同的情况下由于模糊论域的变小从而提高了逼近精度，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。仿真结果证明了方法的有效性。

Abstract: We Propose a multi-model switching control for nonlinear systems based on local T-S (Takagi-Sugeno) 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 under a constant fuzzy rule. The approach and control of the entire nonlinear system is established by the multiple-model switching control. Effectiveness of the proposed method is demonstrated with simulation results.
