Abstract

The present invention relates to a collaborative optimization method for the clarification process of sugarcane juice based on the minimum entropy, which acts on the automatic control system of the clarification process of sugarcane juice. and the relationship of flow changes, divide the clarification system, and divide the clarification system into material subsystem, energy subsystem and information subsystem; according to the material subsystem, the energy subsystem and the information subsystem The relative entropy between the system and the clarified system is minimized, and an objective function is constructed; the objective function is solved, and an optimization result is output. The collaborative optimization method of the sugarcane juice clarification process based on the minimum entropy provided by the present invention realizes the local search ability of the algorithm while taking into account the global search ability of the algorithm, so that the clarification system can be optimal, and the clarification purity and effect can be improved. and efficiency, thereby improving sucrose extraction and final product quality.

Description

technical field [0001] The invention relates to the field of automatic control of sugarcane clarification process and equipment design optimization, in particular to a collaborative optimization method for the clarification process of sugarcane juice based on minimum entropy. Background technique [0002] Guangxi is the main producing area of ​​sucrose, and its sucrose production accounts for more than half of the national sugar production. The sugar industry is the pillar industry of Guangxi. After joining the WTO, the domestic sugar market was gradually liberalized. Affected by factors such as the low level of mechanized and automated production and the impact of imported sugar from abroad, the market competitiveness of my country's sugarcane sugar industry has declined, and it may repeat the mistakes of the soybean and corn industries and be overwhelmed by imported sugar. danger. Facing the pressure of foreign market competition and the high cost of importing foreign adva...
