Sensorless torque control of SyncRel motor drives

IEEE Transactions on Power Electronics, 2000
This 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

Enhancing Low-Speed Sensorless Control of PMSM Using Phase Voltage Measurements and Online Multiple Parameter Identification

IEEE transactions on power electronics, 2020
This article mainly concerns the performance improvement of active flux (AF)-based sensorless control for permanent magnet synchronous machines (PMSMs) in the low-speed range.

Sensorless brushless DC drive controlled by predictive algorithm

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
A 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 Techniques of LIMs

2019
This chapter deals with sensorless (encoderless) control of linear induction motors (LIM). Starting the analysis of the huge state of the art related to sensorless control of rotating induction motors (RIM), the very few contributions to sensorless control of LIM drives are analysed.

Sensorless control of induction motor

2020
ABSTRACT 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

Sensorless control of IM drives

2019
This chapter addresses the fundamental issues of sensorless vector control of induction motor drives. Starting from an historical overview of induction motor control in general, we revisit the two archetypical flux estimators known as the current model and voltage model, as well as their combination into a reduced-order observer. It is demonstrated not

Sensorless speed control of PMSM

2013
In this chapter, the authors are interested in the sensorless control for nonsalient permanent-magnet synchronous motors (PMSM). The models of the PMSM and the problem formulation are given in the first section of the chapter. The controller structure and the main result are presented in the second section.
