Heat flux and plasma parameters in plasma welding by means of velocity shear instability
Industrial applications of plasma welding technology are in spot light in many industries. The flexibility of coupling electric field, magnetic field and parameters in plasma heat flux has been demonstrated in selected pilot scale and plasma welding for metallurgical and parametallurgical purpose. This paper present effect of different parameters: magnetic field, homogenous Direct Current electric field (DC),...

Sliding mode application in speed control of an induction machine coupled in a hydraulic system
In this paper, a nonlinear control of an induction motor (IM) supplied with a photovoltaic generator to assure the level control of two coupled tanks is designed. The global system is decomposed into two separate models thus, coupled are assured by discontinuous command. In the first step, we propose a sliding mode technique to make the speed and the flux control of the IM robust to parameter variations....
