Novel Direct Torque Control Based on Space Vector Modulation WithAdaptive Stator Flux Observer for Induction Motors




INTRODUCTION


Direct torque control based on space vector modulation (DTC-SVM) preserve DTC transient merits, furthermore, produce better quality steady-state performance

In a wide speed range, at each cycle period, SVM technique is used to obtain the reference voltage space vector to exactly compensate the
flux and torque errors.

ABSTRACT
Laser ignition has become an active research topic in recent years because it has the potential to replace the conventional electric spark plugs in engines Compared to conventional spark ignition. Laser ignition allows more flexible choice of the ignition location inside the combustion chamber with the possibility to ignite even inside the fuel spray .Modern engines are required to operate under much higher compression ratios, faster compression rates, and much leaner fuel-to-air ratios than gas engines toda ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

Abstract
Laser assisted direct metal deposition refers to the additive layered manufacturing technology for building components from a
computer-aided design CAD. model. A motion control program, developed from the CAD model of a desired metal component,
is used to control the motion of a laser focal spot to trace all areas of the part, typically a planar layer at a time. Metal powders,
injected into the laser focal zone, are melted and then re-solidify into fully dense metal in the wake of the moving molten pool
created by the las ....etc
