关于线性时变系统的逆

On the Inversion of Linear Time Variable Systems

本文讨论单输入单输出线性时变系统的逆系统问题，给出了可逆性的充要条件和两种降阶逆系统的计算方法，并用例子说明了这些方法。

This paper discusses the invertibility of Single input single output linear timevarying systems.A necessary and sufficient condition for invertibility is derived. A new algorithm for constructing the reduced inverse systems is presented. This algorithm is considerably more efficient and simpler than prerious methods.Finally,an example is given to illustrate the effectiveness of the proposed algorithm.
