Input Delay Analysis and H∞ Control for Networked Control Systems With Finite-Time Stochastic Boundedness

Abstract

This paper investigates the input delay analysis and H_∞ control problem for networked control systems with finite-time stochastic boundedness (FTSB). First, a novel control scheme is used to handle the Markovian jump parameters, and an event-triggered rule is introduced to a networked control system with FTSB, which can ensure the control performance of the system and effectively improve the resource utilization of the networked control system. Simultaneously, a more accurate expression for input delay compared to traditional methods is obtained. Then, the sufficient condition for the networked control system to have FTSB is derived. Additionally, an H_∞ state feedback controller for the stochastic networked control system with FTSB performance is obtained. Finally, an illustrative example is provided to verify the effectiveness of the method proposed in this paper, especially the good control effect of the H_∞ state feedback controller.
