Background
The Localized Scleroderma Quality of Life Instrument (LoSQI) is a disease‐specific patient‐reported outcome (PRO) measure designed for children and adolescents with localized scleroderma (LS; morphea). This tool was developed using rigorous PRO methods and previously cognitively tested in a sample of paediatric patients with LS.
Objective
The purpose of this study was to evaluate the...
This paper gives a review of sensorless methods developed for AC drives' operation at very low and zero speed. The sensorless drives presented in this paper use reluctance spatial anisotropy to track the mechanical rotor position, allowing the use of vector control. To extract the position information additional test signals in form of active vector pulses or continuous high frequency signals are...
This paper describes various methods aimed at tracking the flux and rotor position for cage induction machines without a shaft sensor using specially designed saliencies or natural saliencies. The estimation methods employ a high frequency (HF) signal or test vectors to detect the machine saliency. As is common knowledge, multiple saliencies can cause problems to track only one particular saliency...
