摘要
针对网络控制系统被控对象状态无法直接测量的情况,设计了状态观测器,给出了一种基于误差阈值的确定通信逻辑,应用于基于模型的网络控制系统中,提出了具有确定通信逻辑的网络控制系统结构,建立了系统模型,仿真数例表明加入确定通信逻辑后,在保持系统稳定的情况下,数据发送的次数明显减少,有效地减轻了网络负载。
This paper introduces a determinate communication logic based on the error threshold for networked control systems and its application in the model-based control systems（MB-NCS）.Simulation shows that the introduced determinate communication logic can reduce the data transmission time and lighten the network burden,meanwhile assure the stability for the networked control systems.
