TMS320F280049C: EST_ calls for online RS recalculation

Beat Arnet
Intellectual 890 points

Part Number: TMS320F280049C

Example "is10_rs_recalc", from the Motor Control SDK, makes the following two calls to the EST after obtaining the id reference for Rs-online (EST_getIdRated_A):

EST_updateId_ref_A

and, after running the estimator,

EST_setIdq_ref_A


Are these calls required for the correct operation of the Rs-online calculation? And if so, what is their purpose?

Note that the image from the InstaSPIN Lab7 below seems to suggest that FAST does not require the knowledge of the Idq references.

Thank you.
