| 中文摘要:针对基于非线性时变扰动的一类参数不确定时变广义系统，研究了当系统存在故障时的容错控制问题，首先对系统中存在的非线性扰动在假定其满足Lipschitz条件的前提下进行了线性化处理，然后针对系统中存在的故障建立起故障模型，通过构建Lyapunov方程得到了系统广义二次稳定以及鲁棒稳定的充分条件，并在系统稳定的条件下进一步得到状态反馈容错控制器，从而实现对故障系统的容错控制。最后通过一个数值算例说明所给方法的可行性。 |

| Abstract:The problems of fault-tolerant control were investigated for a class of parameters-uncertain time-varying descriptor systems with nonlinear time-varying perturbation，especially，when the system is in fault.First，the nonlinear perturbation in the system is linearized under the assumption that the perturbation satisfies the Lipschitz condition.Then，a fault model is established for the faults in the system，and sufficient conditions for generalized quadratic stability and robust stability of the system are determined by constructing a Lyapunov equation.Finally，a state-feedback fault-tolerant controller is obtained under the condition of stability of the system.And a numerical calculation illustrates the method feasibility. |
