Insight on the engineering process of the IRO Zero Twist feeder by using Matlab Simulink and the hardware of Beckhoff.
Development of the advanced control algorithms. The speeds at which the loom is running are too high for a classic feedback system. Also the control system should be flexible and smart enough to cope with:
– Different types of yarn
– Different types of bobbins
and different loom types with different widths running at various speeds.
For this development we used the model based approach.
First a plantmodel / digital twin was made of the IRO Zero Twist Feeder and the yarn demand by the loom in Simulink, allowing to start the development of the control software in simulation.
The control model itself consists of an automatic calibration routine to cope with the variablility (of yarns, bobbins and looms) and a learning control strategy to improve keeping the yarn tension constant whilst weaving.
Of the created control model, code was generated and deployed to a controller target for testing on a prototype of the IRO Zero Twist Feeder.
This proved the concept of IRO Zero Twist Feeding showing a significant increase in textile quality.
