    摘要: In a motor control system and method controlled by a d-axis current command value i.sub.ds and a q-axis current command value i.sub.qs, a d-axis voltage command value V.sub.d * and a q-axis voltage command value v.sub.q * are computed on the basis of d-axis current deviation .DELTA.i.sub.d of d-axis current value i.sub.d from the d-axis current command value i.sub.ds and q-axis current deviation .DELTA.i.sub.q of q-axis current value i.sub.q from the q-axis current command value i.sub.qs and on the basis of q-axis inductance value L.sub.q and d-axis inductance value L.sub.d wherein the inductance values L.sub.q and L.sub.d are tuned or adjusted so that the d-axis current deviation .DELTA.i.sub.d and q-axis current deviation .DELTA.i.sub.q approach zero.
