一类异步网络控制系统的分析与建模(英文)

Analysis and Modeling of a Class of Asynchronous Networked Control Systems

针对具有异步时序和状态反馈的异步网络化控制系统,分析了在短时延单包传输、多包传输、单包传输有数据包丢失、多包传输有数据包丢失和长时延单包传输等不同网络条件下网络化控制系统的特点,在此基础上首次提出了各种不同条件下网络化控制系统的统一建模方法。这种包含系统噪声的离散状态空间模型的建立,为网络化控制系统的准确辨识和有效控制奠定了基础。

The characteristics of asynchronous networked control systems with single-packet transmission, multiplepacket transmission, data packet dropout in the presence of short time delays, and single-packet transmission in the presence of long-time delays are analyzed. The asynchronous clock and the state feedback are considered in this paper. Based on it, the uniformed modeling method for networked control systems with the above different network conditions is developed first. The building of discrete state-space models including system noise provides a basis for the exact identification and effective control.
