Radial force control of multi-sector permanent magnet machines for vibration suppression (2017)
Journal Article

Radial force control in electrical machines has been widely investigated for a variety of bearingless machines, as well as for the conventional structures featuring mechanical bearings. This paper takes advantage of the spatial distribution of the wi... Read More about Radial force control of multi-sector permanent magnet machines for vibration suppression.

Robust control of flow separation over a pitching aerofoil using plasma actuators (2017)
Journal Article

We address the problem of controlling the unsteady flow separation over an aerofoil, using plasma actuators. Despite the complexity of the dynamics of interest, we show how the problem of controlling flow separation can be formulated as a simple outp...

Digital Dead-Beat and Repetitive combined control for stand-alone four-leg VSI (2017)
Journal Article

This paper deals with a newly conceived combined control topology. Dead-Beat and Repetitive controllers are proposed to operate jointly in a 4-leg VSI for stand-alone applications. In such mode of operation, dedicated controller has to regulate the i... Read More about Digital Dead-Beat and Repetitive combined control for stand-alone four-leg VSI.

Permanent magnet machine based starter-generator system with modulated model predictive control (2017)
Journal Article

The paper describes a hybrid control scheme for a permanent magnet machine based starter-generator (S/G) system. There has been increased usage of electric drive systems in the transportation sector for increased efficiency and reduced emissions. One...

A fractional delay variable frequency repetitive control for torque ripple reduction in PMSMs (2017)
Journal Article

Based on the internal model principle, repetitive controller (RC) is capable to reduce periodic torque ripple by generating a compensating action that consequently need to be synchronized with the original ripple. However, the synchronization is diff... Read More about A fractional delay variable frequency repetitive control for torque ripple reduction in PMSMs.

Direct flux and current vector control for induction motor drives using model predictive control theory (2017)
Journal Article

The study presents the direct flux and current vector control of an induction motor (IM) drive, which is a relatively newer and promising control strategy, through the use of model predictive control (MPC) techniques. The results highlight that the f... Read More about Direct flux and current vector control for induction motor drives using model predictive control theory.

Stability boundary analysis in single-phase grid-connected inverters with PLL by LTP theory (2017)
Journal Article

Stability analysis of power converters in AC net¬works is complex due to the non-linear nature of the conversion systems. Whereas interactions of converters in DC networks can be studied by linearising about the operating point, the extension of the...

Stability Assessment of Power-Converter-Based AC systems by LTP Theory: Eigenvalue Analysis and Harmonic Impedance Estimation (2017)
Journal Article

Stability analysis of power-converter-based AC systems poses serious challenges not only because of the non-linear nature of power converters, but also because linearisation is not generally applied around a steady-state operating point, as in the DC...

Control of a direct matrix converter with modulated model predictive control (2017)
Journal Article

This paper investigates the use of a model- predic-tive control strategy to control a direct matrix converter. The proposed control method combines the features of the classical Model Predictive Control and the Space Vector Modulation technique into...
