Abstract:
Systems and method for controlling an alternating current (AC) electrodynamic machine ( 390 ) with a variable frequency drive (VFD) ( 380 ) include a control system ( 300 ) with a phase-locked-loop (PLL) circuit ( 382 ) for providing a stator flux angle signal ( 338 ) to the VFD ( 380 ), the PLL circuit ( 382 ) comprising a proportional integral (PI) regulator ( 332 ) providing an output signal ( 334 ); and a feedforward generator ( 350 ) in communication with the PLL circuit ( 382 ), wherein the feedforward generator ( 350 ) tracks a stator flux position of the AC electrodynamic machine ( 390 ) such that the feedforward generator ( 350 ) determines a stator frequency signal ( 352 ) based on stator flux signals ( 308, 310, 312 ) and supplies the stator frequency signal ( 352 ) downstream of the PI regulator ( 332 ), and wherein the stator frequency signal ( 352 ) is summed with the output signal ( 334 ) of the PI regulator ( 332 ) to provide a dynamically adapted output signal ( 335 ) of the PI regulator ( 332 ), and wherein the adapted output signal ( 335 ) is used to determine the stator flux angle signal ( 338 ).

Claim (Index 21):
The control system of  claim 20 , wherein the zero crossings of the stator flux signals are converted to an analog signal using pulse width modulation (PWM), wherein a repetition rate of the pulse train is proportional to a stator frequency of the AC electrodynamic machine.
