Abstract

The invention relates to an intelligent big field irrigation system-oriented intelligent prediction and control method which comprises the following steps: an irrigation process model is built based on hydrological characteristics of an irrigation canal, an irrigation object is calculated after agriculture irrigation information is collected, control deviation is calculated according to the irrigation object and water level data of a sensor, control rate output of a controller is calculated based on the control deviation, an ultra-short feedback intelligent control rate and a current predicted control rate variation quantity are respectively calculated according to the control deviation and the control rate output of the controller, an intelligent prediction control rate is calculated and input into an irrigation process model, water level value is output via the irrigation process model, whether the irrigation object is attained is determined via difference between the water level value and the irrigation object, cyclic operation is performed, and finally intelligent irrigation is achieved after a goal value of a controlled object is accurately attained. The invention provides a stable control method with rapid convergence for agriculture irrigation time lag processes.

Description

technical field [0001] The invention belongs to the field of automatic control, and relates to an intelligent predictive control method for field intelligent irrigation systems, in particular to an intelligent predictive control method based on endocrine ultra-short feedback mechanism and predictive control. Background technique [0002] Compared with traditional manual control, intelligent irrigation mode has the remarkable characteristics of saving water, fertilizer and labor, and can eliminate the adverse effects of human factors on irrigation, which is more conducive to the scientific management of irrigation and the promotion of advanced irrigation technology. The intelligent irrigation mode can promote the increase of crop yield and the construction of family pastures in our country, promote the transfer of labor force and the adjustment of rural economic structure in our country, and it is also conducive to environmental protection. [0003] In order to realize intell...
