An LMI-Based H∞ Control Approach for Networked Control Systems with Deadband Scheduling Scheme

Abstract EN

Due to the bandwidth constraints in the networked control systems (NCSs), a deadband scheduling strategy is proposed to reduce the data transmission rate of network nodes.

A discrete-time model of NCSs is established with both deadband scheduling and network-induced time-delay.

By employing the Lyapunov functional and LMI approach, a state feedback H∞ controller is designed to ensure the closed-loop system asymptotically to be stable with H∞ performance index.

Simulation results show that the introduced deadband scheduling strategy can ensure the control performance of the system and effectively reduce the node's data transmission rate.
