Distributed H∞ Consensus Control of Networked Control Systems with Time-Triggered Protocol

Abstract EN

The analysis and design of traditional networked control systems focused on single closed-loop scenario.

This paper introduces a distributed control approach for the networked control systems (NCSs) with multiple subsystems based on a time-triggered network protocol.

Firstly, some basic ideas of the time-triggered protocol are introduced and a time schedule scheme is employed for the NCS.

Then, a novel model is proposed to the NCS regarding the network-induced delay.

The resulting closed-loop system is time-delay linear system considering a distributed control law.

A sufficient condition to H∞ consensus control is present based on the Lyapunov-Krasovskii function.

Also, the controller design approach towards the given H∞ performance index is given by a cone complement linearization and iterative algorithm.

Finally, numerical examples are given to validate the approach.
