Event-triggered L₂ controller design of networked control systems with quantized measurement

This paper considers L2 control for a networked control system with quantized measurement. The system state is periodically sampled and quantized. An event-triggered transmitter is introduced to determine whether or not the current quantized measurement should be transmitted through the communication channel to the controller. In this event-triggered networked control system framework, a networked controller is designed to guarantee the L2 stability of the closed-loop system. Two numerical examples are given to demonstrate the effectiveness of the proposed method. It is shown that the average transmission interval could be increased substantially while the control performance is maintained. © 2012 Institute of Engineers
