| 摘 要： | 针对一类系统状态、关联项和控制输入均含有时变时滞以及系统带有非线性扰动的不确定关联系统，研究其分散鲁棒容错控制问题．通过构造适当的Lyapunov函数，运用线性矩阵不等式（LMIs）的方法，给出了系统分散鲁棒容错控制的充分条件，以及在此条件下的分散状态反馈控制律，它对执行器发生故障时具有完整性．然后求解一个具有LMIs约束的凸优化问题，作为设计具有尽可能小反馈增益的分散鲁棒容错控制律的系统化方法，从而得到更符合实际的分散鲁棒容错控制律．

| Abstract: | The problem of decentralized robust falt-tolerant control is investigated for nonlinear uncertain interconnected systems with state and input time-varying delays.By conducting proper Lyapunov universal function and using LMIs,sufficient conditions for existence of decentralized robust falt-tolerant stabilization are presented.Based on these conditions,the controller is presented in the case of actuator failures.By solving a convex optimization problem with LMIs constraints,the systematic methods for decentr... |
