摘　　要：研究带有不确定项的广义周期时变系统的二次稳定及其完整性问题。引入广义不确定周期时变系统二次稳定的概念,用广义代数Riccati不等式,给出广义不确定周期时变系统在状态和输出反馈作用下所构成的闭环系统二次稳定,并且当传感器或执行器出现故障时仍能具有完整性二次稳定的充分必要条件。所得结论是广义系统完整性研究成果向一般广义周期时变系统的扩展。最后,通过数值算例验证了所得结论的有效性。Study of uncertain generalized periodic time-varying system two stability and integrity.Introducing general periodically time-varying uncertain system two the concept of stability,generalizes algebraic Riccati inequality,generalized periodically time-varying uncertain systems in state and output feedback under the action of the closed-loop systems consisting of two stable,and when the sensor or actuator failures can still complete with two stable sufficient and necessary condition.The conclusions are generalized system integrity research results to the general periodically time-varying descriptor system expansion.Finally,the numerical examples verify the effectiveness of the obtained conclusions.
