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, using a well known phase transposition in the series connection. At the first, the decoupled torque and flux controller is developed based on variable-structure control (VSC). Then, a sliding-mode (SM) flux obse...

Two algorithms have been extensively studied for motor control: Field Oriented Control (FOC) and Direct Torque (DTC). Both control use a Voltage Source Inverter (VSI) to drive Permanent Magnet Synchronous Motor (PMSM). To prevent short-arm short-circuit accidents when driving PMSM using VSI, dead time is used turn off the TOP BOTTOM switches of each arm at same time. However, this dead-time tec...

ABSTRACT The outer protoplanetary discs (PPDs) can be subject to the magnetorotational instability (MRI) and vertical shear (VSI). While both processes drive turbulence in disc, existing numerical simulations have studied them separately. In this paper, we conduct global 3D non-ideal magnetohydrodynamic (MHD) for PPDs, with ambipolar diffusion instantaneous cooling, hence conductive instabiliti...

This paper presents modeling of an Alternating Current (AC) Photovoltaic (PV) module using Matlab/Simulink. The proposed AC-PV module model is simple, realistic, and application oriented. The model is derived on module level as compared to cell level directly from the information provided by the manufacturer data sheet. DC-PV module, MPPT control, BC, VSI and LC filter, all were treated as a si...

The Hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...

The dependability of power electronics systems, such as three-phase inverters, is critical in a variety applications. Different types failures that occur an inverter circuit might affect system operation and raise the entire cost manufacturing process. As result, detecting identifying problems for devices industry. This study presents short-time Fourier transform (STFT) fault classification ide...

this paper presents the new topology of three phase on line uninterruptible power supply (ups) by employing t-source inverter (tsi) with maximum constant boost pulse width modulation (pwm) control and the results are compared with the conventional uninterruptible power supply (ups). the conventional ups consists of voltage source inverter (vsi) with step up transformer or dc-dc booster which de...

Finite Set Model Predictive Control (FS-MPC) is a widely used technique in power electronic converter applications. One challenge FS-MPC implementation selecting appropriate weighting factors, as there currently no established methodology for finding the best values. An alternative approach to consider cost functions without by Sequential (SMPC). In this paper, performance of SMPC applied induc...
