High harmonic contents of the stator currents due to uncontrolled $x-y$ subspace dramatically overshadow performance switching-table-based direct torque control (ST-DTC) strategy for multiphase drives. The concept ST-DTC based on virtua...

This article presents a postfault control algorithm that minimizes the stator Joule losses in multiphase induction machines under an open-phase fault and for different star connection layouts. The key novelty is can be applied to any configuration of multi- n -phase machine, independently neutral points. latter analytically derived based on space vector representation machine model. In addition...

The proposed paper deals with steady state estimation of a electromagnetic torque ripples and a current waveform of a two-phase induction motor (IM), which is supplied by an three-leg voltage source IGBT bridge connected inverter (VSI). The complex Fourier series analysis of the inverter’s output voltage was made, to obtain an analytical formula of supply voltage waveform. The space phasor theo...

Steady-state analysis of a three phase induction motor can be carried out by using computer simulation software such as MATLAB. From Simulink/Power system block set (PSB) library, the induction motor model can be effectively used to simulate the effects of DC resistance, no-load and blocked rotor tests. These tests are performed on a machine to estimate the values of stator and rotor resistance...

This paper presents a novel strategy for the synchronization of grid-following Voltage Source Converters (VSCs) in power systems with low rotational inertia. The proposed unit is based on emulating physical properties an induction machine and capitalizes its inherent grid-friendly such as self-synchronization, oscillation damping, standalone capabilities. To this end, mathematical model analyze...

in this paper, a Fuzzy logic based direct torque control (DTC) scheme for split phase induction motor (SPIM) is established. The induction motor has two sets of stator three-phase windings spatially shifted by 30 electrical degrees. The major disadvantage of conventional DTC is existence of high torque ripples. In this paper, we used a fuzzy logic controller to overcome this drawback. Simulatio...

Algorithms for induction of concept descriptions from examples are important tools in the fields of machine learning and knowledge discovery in databases. This paper presents an induction algorithm, named PA3, that learns a set of ordered rules from examples. Functionally inspired in AQ and CN2, this algorithm attempts to generalize the learned rules during the induction process and introduces ...

Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...
