Greenhouse Humidity System Modeling and Controlling based on Mixed Logical Dynamical
Greenhouse can provide a favorable growth environment,such as proper temperature,humidity and light intensity for plants.Due to the greenhouse of China having characteristics like its input and output variables being continuous and the states of control equipments being discrete,hybrid system theory is used to describe the greenhouse system.Based on the theory of mixed logical dynamical,the model of greenhouse humidity system is established in this paper,and the real-time greenhouse control can also be achieved by solving control sequence which depends on using optimization performance index.As the experiment result shows,the mixed logical dynamical model can simulate the greenhouse humidity system very well,and the optimal control based on this model can restrict the inside humidity index within a range of settings.
