A novel stability criterion of WSNs measurement and control system with time-delay

Abstract

This paper studies the problems for the stability analysis and controller design of wireless sensor networks (WSNs) measurement and control systems. In order to ensure the stability of the systems, we construct proper Lyapunov-Krasovskii functional and employ integral inequalities to analyze the WSNs measurement and control systems based on Lyapunov theorem. At the same time, in combination with the actual conditions, it makes a concrete analysis of the WSNs measurement and control system in greenhouse with temperature and humidity parameters as the objectives of research. A numerical example demonstrate that the criterion obtained in this paper can make the WSNs measurement and control systems steady, which is better than some published results.
