Hi LiZhanWu,
iQ Fbck can be visualized using "Iq current" recorder in FreeMASTER tool as it is demonstrated in MTRCKTSPNZVM128 development kit software example (AN5327_PMSM_FOC_Sensorless_SingleShunt.pmp file).
In the C source code it is the variable drvFOC.iDQFbck.f16Arg2.
In order to get DQ currents from abc stator currents, clark and park transformations are used.
Those functions are offered by NXP AMMCLIB.
GMCLIB_Clark(&drvFOC.iAlBeFbck,&drvFOC.iAbcFbck);
GMCLIB_Park(&drvFOC.iDQFbck,&drvFOC.thTransform,&drvFOC.iAlBeFbck);
More details can be found in application note AN5327.pdf and AMMCLIB user guide MC9S12ZVMMCLUG.pdf.
Best regards,
Tomas Fedor
