Super-Twisting Sliding Mode Direct Power Control of a Brushless Doubly Fed Induction Generator
IEEE transactions on industrial electronics (1982. Print), 2018This paper proposes and implements a super-twisting sliding mode direct power control (SSM-DPC) strategy for a brushless doubly fed induction generator (BDFIG).

Brushless Operation of a Wound-Field Synchronous Machine Using a Novel Winding Scheme
IEEE transactions on magnetics, 2019This paper proposes a novel winding scheme to generate an additional sub-harmonic magneto-motive force (SH-MMF) component for the brushless (BL) operation of a wound-field synchronous machine.

Brushless Superconducting Generator.
1982Abstract : This report covers work on a flux pump excited brushless superconducting alternator. The flux pump, used to provide the excitation current of the field coils incorporates several features of a machine studied theoretically and reported in an earlier paper.

We derive the mathematical model of this class of motors. Then we design the proposed control schemes in original coordinates, i.e. a dq transformation is not required. We formally solve the velocity and position regulation problems. A pendulum is included as the load in the position control problem. In this chapter we include sketches of the stability

A Novel Approach for Speed and Failure Detection in Brushless DC Motors Based on Chaos
IEEE transactions on industrial electronics (1982. Print), 2019This paper presents an approach developed to quantify the chaotic behavior for the characterization of electromechanical systems. A technique named Signal Analysis based on Chaos using Density of Maxima (SAC-DM) is presented. This technique uses a simple

Brushless Thyristor Excitation Systems.
IEEE Transactions on Power Apparatus and Systems, 1972This paper shows how brushless thyristor excitation systems for large synchronous generators are being evolved in the authors' organisation, outlines the electrical and mechanical advantages that accrue, and includes some results of a digital computer comparison of such systems with other forms of excitation.

Empirical Characterization of a High-performance Exterior-rotor Type Brushless DC Motor and Drive
IEEE/RJS International Conference on Intelligent RObots and Systems, 2019Recently, brushless motors with especially high torque densities have been developed for applications in autonomous aerial vehicles (i.e. drones), which usually employ exterior rotortype geometries (ER-BLDC motors).

A BRUSHLESS SYSTEM FOR POSITION CONTROL
IFAC Proceedings Volumes, 1983Abstract The problems related to the use of a Brushless motor in a position control are analysed. The motor is a P.M. Synchronous motor, for which a magnetically isotropic or anisotropic structure may occur, according to the magnets arrangement in the rotor.The attention is firstly devoted to the drive system prerogatives, which must be suitable for ...
