Flux Weakening Strategy Optimization for Five-Phase PM Machine with Concentrated Windings [PDF]
, 2012 The paper applies an Efficient Global Optimization method (EGO) to improve the efficiency, in flux weakening region, of a given 5-phase Permanent Magnet (PM) machine. An optimal control for the four independent currents is thus defined.

Guiding the Selection of Multi-Vector Model Predictive Control Techniques for Multiphase Drives
MachinesA diverse group of so-called multi-vector techniques has recently appeared to enhance the control performance of multiphase drives when a direct control strategy is implemented. With different numbers of switching states and approaches for estimating the

Direct torque control of multiphase doubly converter-fed asynchronous machines incorporating the harmonic torques [PDF]
, 2018 Doubly fed asynchronous machines have an outstanding property: they can be operated up to twice rated speed delivering full rated torque. This paper presents, for the first time in the literature, a control system for multiphase asynchronous machines fed

Should {\Delta}{\Sigma} Modulators Used in AC Motor Drives be Adapted to the Mechanical Load of the Motor? [PDF]
, 2012 We consider the use of {\Delta}{\Sigma} modulators in ac motor drives, focusing on the many additional degrees of freedom that this option offers over Pulse Width Modulation (PWM). Following some recent results, we show that it is possible to fully adapt

Forced generation of simple and double emulsions in all-aqueous system [PDF]
, 2012 We report an easy-to-implement method that allows the direct generation of water-in-water (w/w) single emulsions. The method relies on direct perturbation of the pressure that drives the flow of the dispersed phase of the emulsions.
