| 摘 要： | 该文针对二维（２－Ｄ）奇异系统的一般模型（ＳＧＭ）探讨２－Ｄ奇异系统的状态空间实现问题。２－Ｄ奇异系统的非因果性，即其传递函数矩阵的非真有理性使得它的实现较２－Ｄ正则系统难得多，文中设法交非真的理论的传递子矩阵变为真有理的传递函数矩阵，在已有的２－ＤＲｏｅｓｓｅｒ模型（ＲＭ）的实现基础上，提出了一种２－ＤＳＧＭ的实现算法。文末举例说明该算法，该算法在关于２－Ｄ奇异系统实现领域中至今也是最新的。

| Abstract: | The state-space realization problem for two-dimensional singular general model (2-D SGM) has been discussed in this paper. Compared with 2-D regular systems, the realization for 2-D singular sysJems becomes more difficult. btecause of their non-causality, i. e. their improper rationality of transfer function matrices. In this paper, the transfer function matrix of 2-D singular systems is converted to be proper- Then, on the basis of the realization of 2-D Roesser model, an algorithm for the realization for 2-D singular general model has been introduced. An example is shown to explain the algorithm. The algorithm is the latest today in the field of realization for 2-D singu1ar systems. |
