| 中文摘要 |
| 本文讨论了工业过程控制系统中操作变量及量测变量的选取问题。首先通过引入一种变量选择矩阵，给出了问题的统一数学表达式，提出了系统能控性、能观性的两种测度，在此基础上给出了变量选择的有效算法。 |
| 英文摘要 |
| In this paper, the problem of selecting manipulated variables and measurement variables is discussed in detail. A kind of socalled selection matrix is introduced to describe the selection problem in a general mathematical form. Two kinds of measures are used to provide quantative information for controllability and observability of linear multivariable systems, and effective algorithms have been suggested to search proper variables according to these measures which seem to be advantageouse on calculation burden in comparing with other methods appeared. This selection method can be used in synthesis and analysis of control systems. |
