چکیده
In this paper, the theory of the ballooning yarn has been adapted to the loop spinning process. The aim of a numerical simulation of high-speed winding process consists in establishing the shape of the curve of rotating yarn in the section between the gripping line of drafting motion rollers and the place where the yarn is wound upon a tube, and in determining the tensile force in the yarn in the said section. The compiled mathematical model serves for analysis and optimisation of boundary conditions of the examined winding process. The method of the determination of the ballooning yarn curve with usage of high speed cameras is used for the verification of the mathematical model. Shape of the ballooning yarn is defined by image analysis from video files.

Although LCL filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. Recently, the single-loop control strategy has beensuggested for L or LC filter based grid-connected inverters. However, the use of single-loopcontrol directly in LCL filter-...

This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...
