：通过共享数据通信网络传输传感和控制信号的网络控制系统（NCS）的应用正在显着增长，这些系统在过去十年中一直是研究的主题。另一方面，多速率采样数据系统已经被研究很长时间了。在本文中，提供了将网络控制系统建模为多速率采样数据系统的条件。之后，利用网络控制系统领域的最新成果，增强了多速率采样数据系统的可控性和稳定性的现有结果。为此，基于系统特征值提供充分的条件，以保持多速率采样数据系统的可控性（稳定性）。将结果与文献中现有的结果进行比较。为了澄清和比较，还包括一个数值示例。
: The application of Networked Control Systems (NCS) in which sensory and control signals are transmitted via shared data communication networks, is growing significantly and these systems have been the subject of research during the last decade. On the other hand, multirate sampled data systems have been investigated since a long time. In this paper, conditions under which a networked control system could be modeled as a multi rate sampled data system are provided. After that, using recent results in the field of networked control systems, existing results for controllability and stabilizability of multi rate sampled data systems are enhanced. For this purpose, sufficient conditions are provided based on the system eigenvalues, to preserve controllability (stabilizability) of a multi rate sampled data system. The results are compared to the existing results in the literature. A numerical example is included as well for clarification and comparison.
