An Improved Finite Control Set Model Predictive Current Control for a Two-Phase Hybrid Stepper Motor Fed by a Three-Phase VSI

Energies, 2022
In this paper, an improved finite control set model predictive current control (FCS-MPCC) is proposed for a two-phase hybrid stepper motor fed by a three-phase voltage source inverter (VSI). The conventional FCS-MPCC selects an optimal voltage vector (VV)

A low‐complexity FS‐MPDPC with extended voltage set for grid‐connected converters

IET Energy Systems Integration, 2021
The conventional finite control set model predictive control (FS‐MPC) for converter control is a well‐studied area, but performance degradation due to the finite candidate vector set is still limiting its practical applications.

Correcting Charge-Constrained Errors in the Rank-Modulation Scheme [PDF]

, 2009
We investigate error-correcting codes for a the rank-modulation scheme with an application to flash memory devices. In this scheme, a set of n cells stores information in the permutation induced by the different charge levels of the individual cells.
