Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
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.

Uncertainty‐aware hybrid model for reliable navigation guidance in prostate biopsy
Abstract Background Prostate biopsy – performed under ultrasound (US) guidance ‐ is the only confirmatory procedure for diagnosing prostate cancer. If several systems aiming at improving the accuracy of tissue sampling for histopathological analysis exist, they often fail to adequately account for patient / tissue motion and deformation during the ...

Self-Commissioning Algorithm for Inverter Non-Linearity Compensation in Sensorless Induction Motor Drives [PDF]
In many sensorless field-oriented control schemes for induction motor (IM) drives, flux is estimated by means of measured motor currents and control reference voltages.

The method presented in this paper provides a practical sensorless solution for estimating both contact force and contact location using only standard joint encoders and an available robot dynamic model. By reformulating the contact estimation problem using a single scalar equivalent contact parameter, the approach enables fast and robust computation ...

Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.

Sensorless Speed Control of IPM Motor
This paper shows techniques to drive a IPM (Interior Parmanent Magnet) motor in all region of speed. That is, a sensorless vector control with a disturbance observer is shown for a normal speed region, a detection method of a pole position is shown at stand still, and for a extremly low speed, a method which produce a required torque is shown.
