Torque ripple reduction of Brushless DC Motors (BLDCs) with concentrated winding is an attractive subject in variable speed AC drives. In ideal BLDC with trapezoidal back-EMF torque …
Gasification is a thermochemical process in which solid or liquid fuels are transformed into synthesis gas through partial oxidation. In this paper, a kinetic model of rice husk gasification …
In order to regulate the output voltage in DC-DC converter systems with step-up function, a Z-source converter has been preferred. In this paper a back-stepping sliding mode controller …
This paper describes the decoupled torque and flux control of a two series connected five-phase Induction Machine (IM) drive that is supplied by a three-level five phase SVPWM inverter…
Direct torque control (DTC) of induction machines (IM) is a well-known strategy of these drives control which has a fast dynamic and a good tracking response. In this paper a nonlinear …
Single phase motors are widely used in indoor and low power industrial equipments. One of the essential problems of single phase induction motors (SPIMs) is their high torque …
PMSMs are mainly controlled using DTC and FOC. However, these methods suffer from relatively high torque and stator flux ripples. This article suggests a model-predictive control …
In order to regulate the output voltage in converter system with four-quadrant characteristic a quasi-Z-Source Converter (qZSC) is preferred. The converter can provide bi-directional …
Surfactants or surface-active agents are molecules with hydrophilic head and hydrophobic tail. They have been widely used as active ingredient in soap and detergent formulations. …
Purpose To propose and adaptive nonlinear controller for adjustable speed sensorless induction motor drive, using a novel adaptive rotor flux observer. The adaptive flux observer …
