Automatic Tuning of Extended Kalman Filter in Sensorless Synchronous Reluctance Motor Drives
A substantial reduction in the human environmental footprint can be achieved through the use of more efficient motors, such as synchronous reluctance motors (SynRM). As low-cost motors, SynRMs are commonly employed in sensorless AC drives.

Development of a Speed Sensorless IM Drives
The primary objective of this paper is to elimination of the problem of sensitivity to parameter variation of induction motor drive. The proposed sensorless strategy is based on an algorithm permitting a better simultaneous estimation of the rotor speed and the stator resistance including an adaptive mechanism based on the lyaponov theory. To study the

Sensorless control of five-phase brushless DC motors
The work developed in this paper presents a comparison between three different phase detection algorithms in order to study the benefits of using each of them when they are applied inside a sensorless rotor position estimation technique. In particular we

Injectionless Sensorless Control of Synchronous Reluctance Machine for Zero to Low Speeds Region [PDF]
An alternative to the high frequency injection approach for sensorless control at zero and low speed region is proposed for synchronous reluctance machines (SyR) using finite-control-set model predictive control (FCS-MPC).

PWM-Based Speed and Position Estimations for Permanent Magnet Synchronous Machines
A PWM-based rotor position and speed estimator is presented in this study. The method is based on the measurement of the current response to conventional space vector pulse width-modulated voltage (SV-PWM) for PMSM drive applications.

Devices and Techniques for Sensorless Adaptive Optics
Minimizing the aberrations is the basic concern of all the optical system designers. For this purpose, a large amount of work has been carried out and plenty of literature can be found on the subject. Until the last twenty years, the large majority of the optical design was relat‐ ed to “static” optical systems, where several opto-mechanical parameters,
