关于可分2－D系统的几个注记

可分２－Ｄ系统是一类具有良好特性的重要的特殊２－Ｄ系统，它在多方面均有重要的应用．本文在已有结果的基础上对具有可分性的２－Ｄ多输入多输出系统在再实现问题、渐近稳定性代数判据、状态观测器设计等方面进行了较为广泛的研究，得到了许多较好的结果．

Some Notes on Separable 2-D System

Separable 2-D systems, i. e. the 2-D discrete systems whose polynmials are separable, are an important special class of 2-D systems, and possess many satisfactory properties and have significant applications in many areas. In this paper, on the basis of existing results we discuss the problens of re-realizations, computation of transition matrix, algebraic criteria of asymptotic stability, and design of state asymptotic observers etc. formulti-input and multi-output separable 2-D spstems. Some results concerned are obtained.
