TMDXIDDK379D: Sensored FOC of 3phase PMSM Variables

Part Number: TMDXIDDK379D

Hi Team,

Posting on behalf of our customer as they would like to deeply understand the CCS code for build level 2, 3 and 4. Most of the variables in the application note below are in per unit. Is there a user manual that goes over the variables and what they mean? In Level 2 and 3, what does the Idref, Iqref, Vdtesting, Vqtesting in the code mean?

Appreciate your inputs on this.

Kind Regards,

Jejomar

  • These variables are described in the code at the declaration, and are not exclusively described in a document. For some one familiar with field oriented control, these names should be intuitive to understand. If this is not so, then would recommend to review the code where the concerned variable is used and the context should help understand its scope.
