LI Ke-wei, ZHANG Rong-biao, XIE Zhi-chao. Stability analysis of time-delay of WSNs measurement and control system[J]. 2009, 28(6): 36-39. DOI: 10.13873/j.1000-97872009.06.023.
the distinct characteristic of wireless sensor networks(WSNs)
based on the analysis of the information transmission model of measurement and control system
the maximum time-delay inequality that makes system asymptotically stable can be derived according to the related theories about stability of Lyapunov.At the same time in combination with the actual conditions
it makes a concrete analyzes of the WSNs measurement and control system in greenhouse with temperature and humidity parameters as the objectives of research.Then the maximum allowable time-delay is calculated by linear matrix inequality(LMI) of Matlab
which meets the stability of the WSNs measurement and control system.The simulation analyses of the example of stability on WSNs measurement and control system in greenhouse show that the maximum allowable time-delay can provide theoretical evidence to assure the stability of the system.
