چکیده

A new method for current control of multiphase drives is presented. The proposed control method is based on a model based predictive controller which minimises a predefined function cost. A voltage vector to minimise the current error is selected. A discrete-time model of the drive is also used to generate the control signals. Simulation and experimental results are provided. These preliminary results confirm the feasibility of the presented method for controlling an asymmetrical dual three-phase ac machine.

Space Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

Implementation of a Novel Brushless DC Motor Drive based on One-Cycle Control Strategy

In this paper, one-cycle control (OCC), as a constant-frequency PWM control strategy for current control of a six-switch brushless dc (BLDC) motor drive is investigated. Developed current regulator is a unified controller and PWM modulator. Employing the one-cycle control strategy, decreases the torque ripple resulted from the conventional hysteresis current controllers and therefore, the vibra...
