Abstract

The invention belongs to the field of robust optimization in the continuous annealing production process, and particularly relates to a novel robust evaluation index and an optimization method based on an improved multi-objective algorithm. The novel robust evaluation index can more accurately represent the size of the robustness, the improved algorithm improves the capability of solving the globally optimal solution, the diversity of understanding is increased, and the robust optimization problem in the continuous annealing production process is more effectively solved. According to the technical scheme, firstly, a novel robust index is put forward, and a continuous annealing process robust multi-objective optimization model is established based on the novel robust index; secondly, introducing a corresponding strategy to improve an original algorithm so as to ensure the globality and convergence speed of optimization; and finally, an algorithm execution result guides efficient operation of a continuous annealing production process.

Description

technical field [0001] The invention relates to an improved multi-objective dragonfly algorithm robust optimization method for continuous withdrawal process, which belongs to the field of continuous withdrawal production process optimization. Background technique [0002] The continuous annealing production line (CAPL) is an important technological process in iron and steel enterprises. It is located in the last process of cold rolling and is a method of heat treatment. In the actual production process, due to the existence of various uncertain factors such as inaccurate parameter measurement, problems such as large fluctuations in strip quality, large energy consumption and low production efficiency often occur, so it is particularly important to optimize its operation. Through the collection and analysis of the continuous retreat process information, calculate and adjust the parameter setting values ​​of the continuous retreat production, and guide the operation of the act...
