Model predictive control-based direct torque control for matrix converter-fed induction motor with reduced torque ripple

CES Transactions on Electrical Machines and Systems, 2021
To reduce the torque ripple in motors resulting from the use of conventional direct torque control (DTC), a model predictive control (MPC)-based DTC strategy for a direct matrix converter-fed induction motor is proposed in this paper.

Electromagnetic force and torque on magnetic and negative-index scatterers [PDF]

Optics Express, 2009
We derive the analytic expressions of the electromagnetic force and torque on a dipolar particle, with arbitrary dielectric permittivity and magnetic permeability. We then develop a general framework, based on the coupled dipole method, for computing the electromagnetic force and torque experienced by an object with arbitrary shape, dielectric ...

Assessment of torque components in brushless permanent-magnet machines through numerical analysis of the electromagnetic field [PDF]

, 2005
For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air gap.
