Analysis and control of networked control systems with both time delay and packet dropout

Abstract

Abstract: The stabilization of Networked Control Systems（NCSs） with time delay and packet dropout is studied. Based on the working mechanism?of Zero-Order Hold（ZOH） in actuator, the NCS is modeled as a control system with input delay. Sufficient conditions for the stability and stabilization of NCS are established by use of the Lyapunov theory and time-delay systems theory. Thus, the control problem of NCSs with both time delay and packet dropout is solved effectively. Numerical example shows the effectiveness of the method.

摘要： 针对网络控制系统中同时存在时延和丢包问题，基于零阶保持器的工作机制，将同时受时延和丢包影响的网络控制系统建模为输入带有时延的控制系统，根据李雅普诺夫稳定性理论和时滞系统理论得出控制系统的时滞相关稳定性条件，进一步基于锥补线性化的方法给出控制器的设计方法，有效解决了网络控制系统中同时存在时延和丢包的控制问题。仿真算例表明所提方法的有效性。
