In this paper, a new variable structure position control law for a Six Phase Induction Machine (6PIM) is proposed. The algorithm based on a time-varying switching line guarantees the existence of sliding mode since the beginning of the shaft motion. Indeed, the surface is initially designed to pass through the initial representative point and subsequently moved towards a predetermined desired surface...

This paper deals with a new variable structure position control law for a Six Phase Induction Machine (6PIM) that is based on time-rotating switching surface. This algorithm guarantees the existence of sliding mode since the beginning of the shaft motion. Indeed, the surface is initially designed to pass through the initial representative point and subsequently moved towards a predetermined desired...
A novel sensor-less algorithm for decoupled control of torque and reactive power of a class of doubly-fed machines like the conventional wound rotor induction machine (DFIM) or the emerging brushless reluctance machine (BDFRM), has been proposed in this paper. The control concept has been derived from the first principles of torque production and magnetisation of the machines and requires only the...
In this paper, a topology for a grid connected generation system based on two doubly fed induction machines is presented. The proposed scheme is implemented using an indirect matrix converter consisting of an input stage and two output stages. The input stage is connected to the grid and provides the required DC voltage for both output stages. Each of the output stages is connected to the rotor of...
This paper presents a novel Direct Torque Control (DTC) of Doubly-Fed Induction Machine (DFIM) based on Indirect Matrix Converter (IMC). The matrix converter allows many advantages compared to the conventional voltage or current source inverters. Functionally the IMC is very similar to the Direct Matrix Converter (DMC) but it has separate line and load bridges. Indirect matrix converter has no electrolytic...
Analysis of six-phase induction motor drive system is presented with emphasis on the electrical faults of the inverter. A simple model has been described to analyses the dynamic behavior of the multi-phase machine under fault condition. Simulation and experimental results are presented to verify predicted behavior for different kinds of faults.
This paper presents a new configuration for direct torque control (DTC) of six-phase induction motor (SPIM). In the proposed method, direct torque and flux control are applied to the SPIM using matrix converter with the conventional three-phase source as its input. The new DTC scheme for SPIM benefits the advantages of both DTC and matrix converter. The simulation results show the effectiveness of...
In this paper, sliding mode control (SMC) is applied to regulate the dq axis currents of a 6 phase induction machine (6PIM). This strategy presents a good alternative in power electronics for electrical drives because of its dynamic properties and its high robustness. The design of the sliding mode control law, defined from the healthy mode model, is based on the linear feedback with switched gains...
This paper proposes a double-fed induction machine with a flywheel energy storage system called the multifunctional flexible power conditioner (FPC). It consists of the doubly-fed induction machine (DFIM) with very large rotating inertia and a voltage-source pulse width modulation(PWM) rectifier-inverter used as an AC exciter. A FPC 10 kW model machine is developed. A simulation model for the model...
In this work a field oriented control (FOC) method is used, in combination with a multilevel inverter, in order to control the speed of an induction machine. A three level diode clamped inverter (DCI) is used, instead of a cascaded multilevel inverter which is the usual solution. A direct stator flux oriented control scheme has been implemented in order to achieve fast and accurate control. Also,...
