Problems solved by technology

In particular, there is a coupling relationship between velocity and tension. If only PID or PID control algorithm with separate integral link is used independently for velocity or tension, then velocity and tension are simply considered to be separate and independent variables, ignoring the two It is difficult to effectively control the speed-tension due to the coupling relationship between

Abstract

The invention discloses a speed-tension coordination control method for jigger fabrics; the method mainly uses a fuzzy control system to compare the sampling speed of a photoelectric coder with the set speed, and compare the tension-detection value of a tension detection device with the set tension, so as to timely adjust the control rules according to the dynamic changes of the errors to subsectionally and alternately control the speed and the tension to respectively obtain a coiling frequency fA and an unwinding frequency fB needed in maintaining the equal linear velocity constant tension of dyeing fabrics; a coiling electromotor and an unwinding electromotor are respectively controlled by a coiling transducer working in speed mode and an unwinding transducer working in torque conversion mode. The method solves the coupling problem between the speed and the tension of the jigger fabrics and makes more accurate speed-tension coordination control of the double-input/double-output, coupled and time-varying non-linear system of jiggers, so as to reduce dyeing color difference caused by instable speed and tension and improve the dyeing quality of fabrics.

Description

technical field [0001] The invention relates to a speed-tension coordinated control method for jigger cloth. Background technique [0002] During the jigger production process, in order to reduce the color difference of fabric dyeing and improve the quality of fabric dyeing, when the fabric passes through the dyeing tank for dyeing, the linear speed and tension of the fabric must be kept constant as much as possible. Therefore, the control of the jigger cloth line speed and tension is particularly important. [0003] The physical model of the main body of the dyeing machine is as follows: figure 1 shown. Cloth rollers A and B are respectively driven by two electric motors. When the jigger runs forward, the fabric gradually withdraws from cloth roller A and is wound onto cloth roller B. Cloth roller A is an unwinding roller, and cloth roller B is an unwinding roller. Winding roller, when the fabric is completely wound on the cloth roller B, the transmission control system ...
