Event-triggered H∞ Control for Networked Control Systems with Packet Dropout Compensation

This paper is concerned with the problem of H∞ controller design for networked control systems (NCSs) with network- induced delay and packet dropout compensation. By introducing the dual communication channels data-backup-based compensation method, a new closed-loop model for continuous-time NCSs, which can receive no less than one control input during a control input updating time interval and select the required input signal according to the priority, is established. By defining new Lyapunov function and established model, an effective stability and controller design criterion are derived to guarantee the H∞ performance of the considered systems. Two illustrative examples are used to show the effectiveness of the proposed compensation method.
