Closed-loop, flux weakening control for hybrid excitation synchronous machines

摘要

The paper presents a closed loop flux weakening controller for Hybrid Excitation Synchronous Machines. The control is achieved though regulation of the voltage amplitude and of the phase angle between voltage and current. An operating point analysis is carried out, in order to determine the dynamic behavior of the drive. Finally, experimental tests are conducted on a prototype of axial flux hybrid excitation machine.
