Abstract: Sensorless zero-speed control of permanent magnet synchronous motors using high-frequency signal injection introduces acoustic noise and vibration, while conventional model-based observers ...
Abstract: This article presents a method for simultaneous sensorless rotation and suspension control in a bearingless motor (BELM). Previous sensorless BELM studies have typically addressed either ...
Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam from ...
