摘　　要：提出了切换模糊时滞组合系统模型,并研究了状态和互联项具有时滞情况下的分散镇定问题.当每个互联子系统中的每个切换子系统具有有限个备选的状态反馈控制器,且单一控制器均不能保证系统稳定的情况下,利用多Lyapunov函数方法给出了时滞相关的矩阵不等式条件和分散切换律设计方法,使系统在所提出的分散切换律和分散控制器下渐近稳定.仿真结果表明了所提出方法的有效性.A model of switching fuzzy time-delay composite systems is presented, and the decentralized stabilization problem is studied for the states and interconnected terms with time-delay. When every switching subsystem of every interconnected subsystem has finite states feedback controllers in a given set of controllers and none of the individual controllers can make the systems stable, the matrix inequalities conditions of delay dependent and the decentralized switching laws design method are provided by using multiple Lyapunov functions method, such that the systems are asymptotically stable under the proposed decentralized switching laws and decentralized controllers. The simulation results show effectiveness of the design method.
