Abstract：Concerning the packets loss problem in greenhouse wireless sensor networks（WSN） measurement and control（M＆C） system, two important parameters in greenhouse environment, temperature and humidity, were decoupled, and a multi-input/multi-output mathematical model of non-coupling was pro- posed. Based on analysis of the structure of greenhouse WSN M＆C system, in which there were time-delay and packets loss during data transmission, the exponential stability condition of the system under the control of temperature and humidity was analyzed according to related theories of exponential stability in network control system. The exponential stability was quantitatively judged by linear matrix inequality of Matlab in order to determine stable feasible solution, and to obtain the exponential stability of the greenhouse WSN M＆C system. The maximum allowable rate of packet loss was obtained in the condition that the stability of the system was assured. The results provide theoretical foundation to establish stable greenhouse WSN M＆C system.
