Sensorless control of deep-sea ROVs PMSMs excited by matrix converters [PDF]

open access: yes, 2005
The paper reports the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, experimental results show that observer-based state-estimation techniques normally employed for sensorless control

Physical properties of the Schur complement of local covariance matrices [PDF]

open access: yes, 2007
General properties of global covariance matrices representing bipartite Gaussian states can be decomposed into properties of local covariance matrices and their Schur complements. We demonstrate that given a bipartite Gaussian state $\rho_{12}$ described

The structure of preserved information in quantum processes [PDF]

open access: yes, 2007
We introduce a general operational characterization of information-preserving structures (IPS) -- encompassing noiseless subsystems, decoherence-free subspaces, pointer bases, and error-correcting codes -- by demonstrating that they are isometric to ...
