一些大系统既包含连续模型又包含离散模型,必须将它们变换成一致的形式。本文讨论定常线性离散系统到等价连续系统的变换以及离散系统的相互变换问题,介绍实现这种变换的特征根法、矩阵对数展式法和逐次逼近法。逐次逼近法在工程设计中较实用。文中给出了各种算法所必须满足的条件。数例表明这些算法的结果良好。
Some large systems contain both continuous and discrete models and must be transformed into a consistent form. This paper discusses the transformation from a stationary linear discrete system to an equivalent continuous system and the mutual transformation of discrete systems. The eigenvalue method, the matrix logarithmic expansion method and the successive approximation method are introduced. Successive approximation method is more practical in engineering design. The paper gives the conditions that various algorithms must meet. Several examples show that the results of these algorithms are good.
