Abstract

This paper is devoted to the co-design strategy of event-triggered scheme and dynamic output feedback controller for a class of discrete-time networked control systems (NCSs) with random time delay. An event-triggered mechanism is given to ease the information transmission. Both the sensor and controller are set with mode-dependent quantizers in the system. A Markov process is used to model the time delay which is used to describe the quantization density. By employing the Lyapunov-Krasovskii functional and linear matrix inequality (LMI), sufficient conditions are obtained for the system. A specific example is given to demonstrate the proposed approach.

Highlights

In recent years, a boom of computer science and technology has led to the increasing role of network control in industry
In [6], the authors propose sequential measurement fusion and state fusion estimation methods to deal with delayed data for clustered sensor networks, since they can handle the data that are available sequentially
The eventtriggering mechanism proposed in the 1990s is more advantageous than the time-triggered scheme, which means that the data will not be transmitted unless condition set in advance is satisfied, and it will reduce the time of accessing network and save the network resources

Summary

Introduction

A boom of computer science and technology has led to the increasing role of network control in industry. In order to save network resources, some literatures have proposed time-triggered mechanism (such as [7,8,9]); this scheme transfers each sample data which reduces the utilization of network bandwidth. In [4, 27, 28], the Markov process is applied to modeling the time delay, in [10, 20], the time delay is used to describe the quantization density in the form of function and the authors investigate the dynamic quantization output feedback controller; in [10], the author takes into account an event-triggered scheme to Journal of Control Science and Engineering u(k) Actuator. In the view of the aforementioned analysis, in this paper, we aim to investigate the co-design strategy of the eventtriggered scheme and dynamic output feedback controller.
