Programmable Logic Controllers (PLCs) have been established as standard devices for automation and process control since the 1990s. Although a lot of research work has been done on the field of controller modeling and verification, it is still daily practice that control software is manually developed without applying formal validation methods. On the other hand, controller modeling is often seen...
In this paper an interface designed for developing and studying a process of robotic arc welding, is described. The interface has been implemented in Labviewtrade environment. The process consists in the control of a SMD (Shaped Metal Deposition) system that is an innovative method for rapid manufacturing of metal objects. The system developed can also be used just to control arc process of deposition.
This paper presents some key issues in fiber-optic interferometric magnetic field sensors. Practically applicable methods to design and implement fiber-optic Michelson interferometer and transducers are described with experimental verifications. Detection scheme of traditional hardware demodulation is improved, and a new software demodulation method is addressed. Transducers were implemented by using...
