Load Torque Observer for Minimising Torque Ripple in PMSM
Permanent magnet synchronous motors generate parasitic torque pulsations owing to distortion of the stator flux linkage distribution and variable magnetic reluctance at the stator slots. The consequences are speed oscillations which deteriorate the performance drive in various applications.

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Design of Model Predictive Torque Control (MPTC) for Speed Control 3 Phase Induction Motor with Robust Stator Flux Observer [PDF]
The induction motor is a desirable alternative to the direct current motor in many applications because it is rugged, reliable and economical. However, control of the induction motor is more complex than the direct current motor, this is caused by the ...

Predictive current control of asynchronous machines by optimizing the switching moments [PDF]
In this paper a model-based predictive control (MBPC) scheme for the current control of induction machines is presented. The controller directly selects the optimal switch state of the inverter.
