Abstract

The invention belongs to the field of information control and relates to an immunological data drive control method and equipment for solving a polyester industrial yarn winding system control problem. The immunological data drive control method combines a data drive control mechanism with a biological regulation mechanism, and can implement closed-loop control under the situation that the accurate model of a controlled target is unknown; when an ideal control effect is given, the control method can rapidly use the practical data of a closed-loop system, can conduct data drive control to the system through the data and can satisfy the dynamic performance requirement of the system under the effect of immunological regulation. The equipment for solving the polyester industrial yarn winding system control problem is configured to be controlled through the immunological data drive control method. Since the accurate model of a winding machine is unknown and the dynamic requirement of a user on the system is high, the equipment which is configured with the immunological data drive control method is used for control.

Description

technical field [0001] The invention belongs to the field of information control, and relates to an immune data-driven control method and equipment for solving the control problem of polyester industrial yarn winding system. Background technique [0002] The existing production technology and method of polyester industrial yarn mainly focus on two aspects of one-step method and two-step method. Among them, the one-step method is widely used because of its high production efficiency and the advantages of high strength, high modulus and low shrinkage of the produced industrial yarn. The one-step method includes four basic steps, solid state polymerization, melt spinning, stretching heat setting and winding forming. As the last step, winding forming plays an important role in the mechanical, heat resistance, dyeing and other properties of industrial yarns. role. The winding forming process mainly depends on the winding machine. Due to the continuous changes in the process var...
