Abstract

The invention discloses an extreme random tree furnace temperature prediction control method based on longicorn beard search, and belongs to the field of furnace temperature prediction and control inthe industrial combustion process. By establishing the regression relation between the key variables influencing the temperature and the temperature of the combustion chamber, the predicted value of the furnace temperature in the combustion chamber is obtained in real time, and the prediction precision of the furnace temperature reaches + / -1.5 DEG C. In consideration of low control precision of anoriginal system, a longicorn beard search algorithm is designed, a secondary performance index function commonly used in predictive control is selected as a fitness function of longicorn, and an optimal control quantity is searched through an olfaction search mechanism of the algorithm, so that the control effect of the whole system is better.

Description

technical field

[0001] The invention belongs to the field of furnace temperature prediction and control in the industrial combustion process, in particular to an extreme random tree prediction control method based on longhorn beetle search. Background technique

[0002] With the increasingly stringent control of environmental pollution, the effective treatment of low-concentration volatile organic compounds (Volatile Organic Compounds, VOCs) from petrochemical, papermaking, paint, printing and dyeing and other industrial production has received great attention in China. At this stage, the most commonly used equipment for VOCs treatment in my country is regenerative thermal oxidizer (Regenerative Thermal Oxidizer, RTO). The traditional RTO adopts simple PID control for the temperature in the combustion chamber, while the oxidation furnace is essentially a large inertia, large lag and multivariable nonlinear system. When the working conditions in the combustion chamber change,...
