Permanent magnet synchronous motors feature high power density, high torque to inertia ratio and high conversion efficiency. These characteristics made them advantageous to use in specific applications such as robotics and traction. However, one of the major drawbacks of these motors is the torque ripple, being especially harmful when a high performance position and speed control is required. Usually,...
Nowadays, besides the rapid growth of different areas like the mechanical and electrical ones, it is possible to identify a particular effort to develop new motors including new electrical drives and control systems. Additionally, these equipments are being designed to give them the maximum efficiency as the energy cost is continuously increasing. With this in mind, some results related to a particular...
This study presents a performance analysis of a neural observer applied to speed and radial position controls of an induction-type bearingless motor with divided windings. The speed and radial control actions are carried out in conjunction with current control in the windings. The neural flux observer aims at compensating possible parametric variations of the machine caused by agents such as temperature...
