Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
, 2011 The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

Real time control of the sawtooth period using EC launchers [PDF]
, 2009 Tokamak plasmas operating at high performance are limited by several MHD instabilities. The sawtooth instability limits the core plasma pressure and can drive the neoclassical tearing mode unstable, but also prevents accumulation of impurities in the ...

Power Smoothing Control in a Grid-Connected Marine Current Turbine System for Compensating Swell Effect [PDF]
, 2013 Variations of marine current speed may lead to strong fluctuations in the power extracted by a marine current turbine (MCT). During short-time period, swell effect is the main cause for the current speed variations.

The current framework for tobacco control [PDF]
New South Wales Public Health Bulletin, 2001 Smoking causes one-third of all cancers and accounts for around 6600 cancer-related deaths in Australia each year. This article describes the draft Tobacco Action Plan 2001–2004, produced by the NSW Department of Health, which aims to improve people’s health by eliminating or reducing their exposure to tobacco.
