Abstract

The invention relates to an intelligent configuration method for technological parameters in a polyester fiber production process. The method is characterized in that the performance indexes of the expected polyester fibers are inputted into a trained improved SA-PSO-ELM algorithm model, and the trained improved SA-PSO-ELM algorithm model outputs the technological parameters in the production process of the expected polyester fibers; the improved SA-PSO-ELM algorithm model is characterized in that a weight value and a threshold value between an ELM network input layer and a hidden layer are used as the particles of a PSO algorithm; a mean square error function is used as a fitness function of a PSO algorithm, the PSO algorithm is adopted to optimize the ELM algorithm, meanwhile the difference value of the maximum fitness and the minimum fitness of the initial group particles of the PSO algorithm is used as the initial temperature in the improved SA algorithm, and the improved SA algorithm is adopted to optimize the PSO algorithm; and during training, the performance indexes of historical polyester fibers and the production process technological parameters are used as input items and output items of the improved SA-PSO-ELM algorithm model. According to the present invention, the production process technological parameters can be directly obtained according to the expected fiberperformance index, the process is simple, the consumed time is short, the configuration result stability is good, and the precision is high.

Description

technical field [0001] The invention belongs to the technical field of intelligent control of polyester fiber production, and relates to an intelligent configuration method for process parameters of polyester fiber production process. Background technique [0002] Polyester fiber has the advantages of high strength, high modulus, small elongation, heat resistance, impact resistance and fatigue resistance, etc. It has a very wide range of applications in the fields of cords, locks, automobiles, seat belts, light box advertising cloth and tire rubber. Due to the excellent performance and low cost of polyester fiber, it has become the four major rubber skeleton materials together with cotton fiber, steel wire and viscose strong wire. In recent years, my country's automobile industry has developed rapidly, the radialization rate of tires has gradually increased, rubber industry products have been continuously adjusted and upgraded, and the demand for polyester fibers and their p...
