Abstract
A method of parameter estimation for a PMSM (permanent magnet synchronous motor) includes: iteratively revising an estimate of an inductance parameter of the PMSM, until the estimate either converges to a predetermined accuracy level or diverges; and controlling a magnitude of phase currents injected into the PMSM during each iteration of revising the estimate of the inductance parameter. Additional methods of PMSM parameter estimation are described, including rotor flux linkage estimation.
