Carbon fiber precursor jet stretching process based on data driving cooperative intelligent control

Abstract

The invention relates to carbon fiber precursor jet stretching process based on data driving cooperative intelligent control. The process route is as follows: spinning melt is accurately metered through a metering pump, enters a spinneret assembly and then enters coagulating bath after being extruded by a jet; a certain ratio of jet stretching is achieved under cooperative intelligent control of a coagulating bath guide roller; and the spinning melt leaves the coagulating bath finally. The carbon fiber precursor jet stretching process based on the data driving cooperative intelligent control is composed of biological intelligent controller design process based on data driving, and intelligent cooperative optimal control process based on multiple-component data collaboration. According to the biological intelligent controller design process based on the data driving, an endocrine ultra-short loop feedback biological intelligent controller is adopted for a controller, data driving improvement is carried out on the endocrine ultra-short loop feedback biological intelligent controller, and the endocrine ultra-short loop feedback biological intelligent controller is designed without dependence on object models; and according to the intelligent cooperative optimal control process based on the multiple-component data collaboration, the intelligent cooperative optimal control of jet stretching ratios is achieved through collecting other spinning component data with cooperative relations and carrying out cooperative optimal computation on the data.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a carbon fiber precursor stretching process based on data-driven collaborative intelligent control. Background technique [0002] Carbon fiber is a new type of high-performance fiber material with a series of excellent properties such as high specific strength, high specific modulus, high temperature resistance, fatigue resistance, corrosion resistance, radiation resistance, heat transfer, electrical conductivity, noise reduction, shock absorption and low relative density. performance. Polyacrylonitrile-based carbon fiber has the best comprehensive performance, accounting for more than 90% of the total production of carbon fiber at home and abroad. At present, many domestic and foreign scholars are studying how to further improve the performance and quality of polyacrylonitrile precursor. [0003] The production and preparation process of polyacrylonitrile...

Problems solved by technology

At present, for some relatively complex industrial production objects, it is often impossible to establish an object model or there are large errors in modeling due to many unclear or random factors involved in the object mechanism.

Model-based design methods of traditional controllers are not up to the task
