Industrial rubber compound Mooney viscosity soft measurement method based on integrated immediate learning

Abstract

The invention relates to an industrial rubber compound Mooney viscosity soft measurement method based on integrated immediate learning. The method is used for online prediction of Mooney viscosity in the industrial rubber compound process. According to the method, Gaussian process regression (GPR) is used as a local modeling technology; in combination with similarity disturbance and a multi-modal disturbance strategy of an input sample, the diversity of instant learning is excited; secondly, an instant learning base model meeting diversity and accuracy is constructed on the basis of evolutionary multi-objective optimization, and finally, fusion of the instant learning base model is realized and a final Mooney viscosity predicted value is obtained by introducing an adaptive integration strategy of a limited mixing mechanism. According to the method, the problems that the cost is increased and the product quality is difficult to improve due to acquisition lag of the Mooney viscosity value in the rubber mixing process are solved, and high-precision online real-time acquisition of the Mooney viscosity is realized.

Description

technical field [0001] The invention relates to the field of batch process soft measurement modeling and application, in particular to a method for soft measurement of Mooney viscosity of industrial mixed rubber based on integrated real-time learning. Background technique [0002] The rubber and tire industry plays an important role in the national economy, and one of the key links is rubber compounding. Rubber compounding is a typical batch industrial process, and online detection of key parameters is a necessary condition for process control and optimization, as well as a key measure to ensure product quality and safe operation of the production process. In the rubber mixing, various compounding agents are added to the raw meal according to the technical formula, and complex chemical reactions are carried out in the mixer to prepare synthetic rubber. The whole process is controlled by the PLC controller to complete the production process of the mixed rubber. In order to o...
