| 摘 要： | 针对具有输出反馈的网络控制系统，研究了基于模型参考控制器的网络控制系统稳定的条件，提出了一种利用被控对象的信息设计系统参考模型，从而降低网络传输的数据量，以适应网络传输需求的控制方法。文章给出并证明了在这种输出反馈控制条件下，网络控制系统稳定时所应满足的充分必要条件。通过Matlab对典型控制对象进行了仿真实验，表明了该结论的正确性和有效性。

| Abstract: | In this paper we study the stability conditions of the Model--Based Network Control System with output feedback plants. The Model- Based Network ControlSystem uses knowledge of the plant dynamics to reduce the number of packet exchanges and thus the network traffic. Necessary and sufficient conditions for stability are derived for the presented setup in terms of the update time h and the parameters of the plant and of its model. As an example to verify the proposed method, a model controller based Matlab typical plants are considered. The simulation results show that the proposed methods are feasible and effective. |
