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 26):
The system of  claim 24 , wherein the output signal of the PI regulator represents an angular frequency of the stator flux signals which is summed with the stator frequency signal of the feedforward generator providing an adapted output signal of the PI regulator representing an adapted angular frequency of the stator flux signals.
