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

Analysis of multistability, hidden chaos and transient chaos in brushless DC motor
, 2020The dynamics of brushless DC motor (BLDCM), a type of permanent magnet synchronous motor (PMSM) is investigated. The dynamical model of the BLDCM is compared to a mostly used model of PMSM.

Permanent-magnet motors for brushless operation
IEEE Transactions on Industry Applications, 1990The design considerations for permanent-magnet motors intended for brushless operation are discussed. Two rotor configurations are described: the imbricated rotor and the segmented rotor. The segmented rotor is designed specially for high-speed operation.

Quadratic programming in control of brushless motors
Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2002A new torque control strategy for brushless motors with minimum torque ripple and minimum copper losses while maintaining the phase currents under magnetic (or current) saturation is presented. The optimal control, a nonlinear map from desired torque and position to the motor's phase currents, is the closed form solution to a quadratic programming ...

A Hybrid Model of a Brushless DC Motor
2007 IEEE 22nd International Symposium on Intelligent Control, 2007This paper presents a novel approach to modeling of a Brush-Less Direct Current Motor (BLDCM) driven by an inverter using hybrid systems theory. Hybrid systems combine continuous and discrete (event-based) dynamics, which is exactly the case in an inverter-driven BLDCM.

Brushless DC (BLDC) motors, also called permanent magnet synchronous motors, are used in direct-drive applications mainly due to their large torque producing capability. Compared to conventional DC motors, they have no brushes or mechanical commutators, which eliminates the problems due to mechanical wear of the moving parts [68, 74].
