Neural Network-Based System Identification and Controller Synthesis for an Industrial Sewing Machine
The purpose of this paper is to obtain an accurate nonlinear system model to test various control schemes for a motion control system that requires high speed, robustness and accuracy. An industrial sewing machine equipped with a Brushless DC motor is considered. It is modeled by a neural network that is configured as an output-error dynamical system. The identified model is essentially a one s...
متن کاملPattern morphology in the elastic sewing machine
We present results from a numerical investigation of the coiling patterns obtained when a slender elastic rod is deployed onto a moving substrate. The Discrete Elastic Rods method is employed to explore the parameter space, construct phase diagrams, identify their phase boundaries and characterize the pattern morphology. The various length scales of the patterns are primarily set by the gravity...
متن کاملAdaptive Control of an Electromagnetically Presser-Foot for Industrial Sewing
This study describes some possibilities of setting up an adaptive control method for an electromagnetically actuated presser-foot in an industrial high-speed sewing machine. The control of fabrics feeding in sewing machines is difficult not only because of the complexity of relations between the intervening variables (material properties, sewing speed), but also because in many operations a var...
متن کاملA numerical investigation of the fluid mechanical sewing machine
A thin thread of viscous fluid falling onto a moving belt generates a surprising variety of patterns depending on the belt speed, fall height, flow rate, and fluid properties. Here, we simulate this experiment numerically using the discrete viscous threads method that can predict the non-steady dynamics of thin viscous filaments, capturing the combined effects of inertia and of deformation by s...
متن کامل“ Pattern morphology in the elastic sewing machine ” Mohammad
In the main text, we noted that the shape parameters (characteristic length, Λ, and loop radius, Ro) of the patterns only depend weakly on the deployment height. To resolve this height dependence of the pattern length scales, we have performed a series of numerical simulations where we have varied the normalized deployment height, H̄, while keeping the gravito-bending length fixed at Lgb = 3.3 c...
