中文摘要： 通过协同形状控制实现分布式驱动变形翼在整个变形过程中的连续与平滑变形，对提高变体飞行器气动性能具有重要意义。目前已有的协同控制研究成果不适用于分布式驱动变形翼这类具有复杂非线性耦合的多智能体系统。本项目提出了一种基于代数图论和仿射T-S模糊关联模型的协同变形控制律设计新方法。对一类具有代表性的分布式驱动变形翼建立非线性耦合多智能体系统模型；以此为基础构建系统的高精度仿射T-S模糊关联模型；用图的概念描述模型中的复杂耦合关系。针对变形翼仿射T-S模糊关联模型，基于代数图论和仿射T-S模糊模型理论，以线性矩阵不等式方法为框架，研究变形翼的鲁棒协同变形控制律设计方法，保证变形翼在整个变形过程中的连续、平滑变形。充分利用代数图论中特殊矩阵的性质并结合耦合项变换方法，探讨协同变形控制律设计条件的降维方法，以获得低维控制律设计条件，提高理论的实用性。在分布式驱动变形翼实验平台上验证主要理论成果。

英文摘要： Distributedly-actuated morphing wings need to be dirven by cooperative morphing controllers to achive continuous and smooth shape changing during the whole morphing process, which is of siginificant importance for enhancing aerodynamic performance of morphing aircraft. The existing research on cooperative control is not appliable to distributedly-actuated morphing wings, which is a kind of complex nonlinear coupled multiagent system. This research project proposes a new method to design the cooperative morphing controller based on algebraic graph theory and affine T-S fuzzy models. The nonlinear coupled multiagent system model of a typical kind of distributedly-actuated morphing wings is to be constructed. Based on this, the interconnected affine T-S fuzzy model with high accuracy will be derived, and the complex couplings will be described by graph. Based on algebraic graph theory and affine T-S fuzzy model theory, in the framework of linear matrix inequality method, the design method of robust cooperative morphing control rules is investigated to guarantee the morping wing to reach continous and smooth shape during the whole process. Then, by using the properties in algebraic graph theory and the coupling transformation approach, the dimensionality reduction of the cooperative control design conditions is to b
