| Abstract: | Aiming at the problems of instability and poor adaptability of the control algorithm of the greenhouse micro-spraying system,in this study,a smooth switching control algorithm was designed by using fuzzy rules.The step modeling method was used to set up the mathematical model of micro spray volume and air humidity,which simplified the greenhouse air humidity model.Finally,WiFi and ZigBee transmission technology were combined to build the greenhouse remote control system.The simulation results of Matlab/Simulink showed that the fuzzy switching control strategy had smaller overshoot and higher stability than the traditional fuzzy PID control,and could achieve better control effect.At the same time,the actual operation results showed that the packet loss rate of greenhouse micro-spray control system was less than 15%,and the greenhouse air humidity could be controlled at about 89%.The operation was stable and met the requirements of greenhouse air humidity control,which realized the precise control of greenhouse air humidity,and provided a solution for the development of agricultural fine control. |
