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.

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]
, 2006 Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...

Sensorless sensing with WiFi [PDF]
Tsinghua Science and Technology, 2015 Can WiFi signals be used for sensing purpose? The growing PHY layer capabilities of WiFi has made it possible to reuse WiFi signals for both communication and sensing. Sensing via WiFi would enable remote sensing without wearable sensors, simultaneous perception and data transmission without extra communication infrastructure, and contactless sensing ...
