Because wide-width Stenter is an important indicator of the quality of the dyeing and finishing process, precise quantitative design parameters and the heat of the processing process play an important role in improving product quality and production efficiency. During the heat-setting period, wide-width Stenter understands the thermoplastic mechanism of elastic knitted fabrics. From the elastic dynamics and thermodynamic equations, elastic knitting sets the mathematical model weight and width Stenter process of the door with thermal treatment.

How to ensure the stability of the wide Stenter's control system

The actual wide Stenter experiment was carried out to verify the validity of the model. By pointing to the existing heat regulation device, the mathematical model of the speed control system and the vehicle speed control system were established, the controllers of each control system were designed, and through simulation and The experimental method verifies the model, as well as the effectiveness and rationality of the control scheme, and understands the correlation between process parameters and quality indicators in the heat setting process.

Consider the coupling relationship between variables, and simplify the configuration process. Thermal system and temperature are used as manipulated variables. Different weights are used as the water content of the control variable. The mathematical model of system multivariable control is used to understand the relative gain to correctly match. Variables, and design the controller's dynamic destination to realize the decoupling control of the multi-variable system quality, effectively eliminate the correlation between the weight and moisture content control loop, and improve the stability of the heat setting control system.

The Flat Screen Printing Machine Factory develops a quality control system through heating. The Wang configured as a development platform. The interface for the heat setting of the quality control machine of the human-computer interaction system is designed to be used as a wide Stenter for parameters and quality indicators. Research modeling technology and system control multivariable quality control heat set an effective reference, which is very important for improving product quality to reduce energy consumption production, the parameter optimization and control algorithm based on the results of particle swarm optimization is feasible.
