Problems solved by technology
The initial construction cost of water and fertilizer integrated equipment is high, and the accuracy of fertilization is related to the flow rate. Due to the limitation of the fertilizer absorption capacity of the Venturi fertilizer absorber, the fertilization accuracy is higher when the flow rate is large, but the fertilization accuracy fluctuates greatly when the flow rate is small
However, the fertilization equipment with large flow rate has higher initial cost and operating cost.

The invention discloses a multi-target accurate fertilization control parameter optimization method for a water and fertilizer integrated machine. The method comprises the following steps of firstly,establishing a multi-target accurate fertilization control parameter optimization mathematical model; and then solving a multi-objective optimized Pareto optimal solution set of the mathematical modelestablished in the step 1, i.e., solving a balanced combination between precision control and energy consumption of fertilization control of the water and fertilizer integrated machine, and providingan optimal solution set for selecting design schemes suitable for different actual conditions. According to the invention, a distributed grey wolf multi-objective optimization algorithm based on Pareto optimization is adopted; the multi-objective accurate fertilization control parameter optimization problem is solved; and in order to adapt to different design actual requirements, the applicability of the water and fertilizer integrated machine in actual application is improved.
Description
technical field [0001] The invention belongs to the technical field of agriculture and garden irrigation, and relates to a multi-objective precision fertilization control parameter optimization method, in particular to a multi-objective precision fertilization control parameter optimization method for a water and fertilizer integrated machine. Background technique [0002] The water and fertilizer all-in-one machine is an important equipment for modern facility agriculture, which provides a basis for realizing precise control of fertilization and improving the level of planting and management of modern agriculture. The initial construction cost of water and fertilizer integrated equipment is high, and the accuracy of fertilization is related to the flow rate. Due to the limitation of the fertilizer absorption capacity of the Venturi fertilizer absorber, the fertilization accuracy is higher when the flow rate is large, but the fertilization accuracy fluctuates greatly when the...
