Abstract: Based on the analysis of the permanent magnet synchronous motor (PMSM) mathematical model, a PMSM rotor field-oriented double closed-loop vector control system is constructed. Aiming at the ...
An advanced method of open-loop speed control devised at Control Techniques is now available on its flag-ship range of AC drives, Unidrive SP. Rotor Flux Control (RFC) is seen as a major advantage in ...
