摘要本文研究了线性切换系统无稳定和二次稳定的动态输出反馈干扰解耦问题。首先研究了一类线性系统的同时（C，A，B）-对，它包含同时（A，B）-不变子空间及其对偶同时（C，A）-不变子空间的概念。其次，利用同时（C，A，B）对的概念，建立了线性切换系统动态输出反馈无稳定性干扰解耦问题，并给出了其可解性条件。进一步研究了扰动解耦切换系统的二次稳定性问题。
Abstract In this paper two disturbance decoupling problems without stability and with quadratic stability via dynamic output feedback for switched linear systems are investigated. Firstly, simultaneous (C, A, B)-pair which incorporates both the concept of simultaneous (A, B)-invariant subspace and its dual simultaneous (C, A)-invariant subspace for a family of linear systems are investigated. Secondly, disturbance decoupling problem without stability via dynamic output feedback for switched linear system is formulated and it's solvabililty conditions are presented by using the concept of simultaneous (C, A, B)-pair. Further, the quadratic stability problem for disturbance decoupled switched system is also investigated.
