Part Number: TMS320F28377S
Hi,
on the DMC MATH there are 2 routines for flux and speed estimation on IM. The routines (really coded as macro) compiles for IQ vars or floating point, depending on device used.
On this point, I have 2 questions:
- on a floating point device, the input quantities (current, voltages to be written in IQsS, IDsS, UQsS, UDsS fields) should be in P.U. or can be in physical units (volt, ampere)?
- the values to be written on the former input fields should be (as the name implies, and as indicated on the documentation) d,q variables after the Park transform (which makes no sense, in my understanding) or, as appear also in the block diagrams of the AN sprabq1.pdf (which explains the use of those lroutines for the CLA) really alpha/beta values after the Clarke transform?
