控制系统数学模型的统一性研究

A study on the model unitarity of controlled systems

采用一种等价的δ算子代替离散时间系统中的平移算子，使连续时间系统与离散时间系统的数学模型得到统一；并讨论了离散时间系统与其对应的连续时间系统之间的某些内在关系．

An equivalent δ-operator is used substituting the transfered operator in the discrete-time systems, so the controlled models of discrete-time and continue-time systems can be united. And some internal relation between this two kinds of models is discussed.
