Sensorless control of PMSM drives
2019When compared to induction motors, permanent magnet synchronous motors (PMSMs) feature higher torque density, improved efficiency and increased constant power speed range. These distinct advantages have resulted in PMSMs being employed in a myriad of industrial applications. Traditionally, the open -loop V/f control scheme has been the preferred method

Sensorless Real Time Control (RTC)
3rd IEEE International Symposium on Sensorless Control for Electrical Drives (SLED 2012), 2012A new Brushless Real Time Control (RTC) method for electric motors or generators is an evolution in Sensor-less control. Very different from any derivative of Field Oriented Control (FOC), RTC uniquely eliminates all control uncertainty, including the extraneous shaft connected resolver for the specific purpose of measuring speed-position (i.e., Sensor-

Pseudo Sensorless Control of PMSM
2006 12th International Power Electronics and Motion Control Conference, 2006Pseudo sensorless permanent magnet synchronous motor torque and flux tracking control algorithm is presented. Proposed approach addresses the problem of operation at zero, low and up to nominal speed. The information of flux is extracted using a nonlinear closed loop rotor flux observer combined with the information obtained from hall sensors, which ...

Sensorless control of induction motors
IEMDC 2001. IEEE International Electric Machines and Drives Conference (Cat. No.01EX485), 2002A sensorless torque control system for induction motors was developed in this research. The system allows for fast and precise torque tracking over a wide range of speed. Unlike most research in the area, the authors used an induction motor model that adapts its parameters to the operating conditions.

Sensorless Control Technique for BLDCM
2011 International Conference on Control, Automation and Systems Engineering (CASE), 2011Brushless DC motor system, the rotor position signal is essential for the normal operation of the entire system. Past rotor position sensor signal is detected by the position, but sensors are more affected by environmental drawbacks. Currently, no position sensor control technology has become a hot topic.

Sensorless torque control of SyncRel motor drives
IEEE Transactions on Power Electronics, 2000This paper describes a direct self-control (DSC) scheme for synchronous reluctance motor drives. The presented DSC scheme develops a new torque control methodology that does not require any position transducer to synchronize the stator current vector with the rotor. Such a control strategy differs from the conventional DSC approach in order to fit some

Sensorless brushless DC drive controlled by predictive algorithm
2009 35th Annual Conference of IEEE Industrial Electronics, 2009A digital speed and high resolution position identification algorithm, suitable for brushless DC (BLDC) drives, is presented in the paper. The proposed digital algorithm is synthesized by using the Popov Hyperstability Theory, by means of the current signal samples.

Sensorless control of induction motor
2020ABSTRACT AC drives based on fully digital control have reached the status of a maturing technology in a broad range of applications ranging from the low cost to high performance systems. Continuing research has concentrated on the removal of the sensors measuring the mechanical coordinates (e.g. tachogenerators, encoders) while maintaining the cost and
