TMS320F2800132: foc, sensorless, pmsm

Part Number: TMS320F2800132
Other Parts Discussed in Thread: TMS320F28027, , TMS320F28335

 

In 2016 I developed a FOC SENSORLESS control for PMSM motors starting from the AppNote spraby9.pdf made by TI for TMS320F2803x and transferring it to TMS320F28027 (model + small).
In this AppNote the observer of the rotor position, that is the difficult part of the work, exploited a library provided by TI. This library has proven itself well suited to the application it was a fan of.
The microp. it was adequate and on the occasion I also added active PFC control.
We are producing this product since 2017 and there are no issues.

Right now I'm considering using TMS320F2800132 to do the same job (FOC+SENSORLESS+PMSM).
Since the "132" is FPU and the "28027" fixed point, the library used with "28027" I really don't think is usable, so I come to the question, how to do?

Furthermore, given the TI.COM site for FPC-SENSORLESS-PMSM, the AppNote spraby9.pdf for fixed point and sprabq4.pdf for
TMS320F28335 which is FPU, can I think that sprabq4.pd is also good for TMS320F2800132? can I think that Ti.com always supplies the observer in the form of a library?

Thank you

    All of the libraries including IQmath library can be used for F2800132. The codes on F28027 can be implemented without much more changes on F2800132 directly.

    Yes. You can set the IQmath library to floating point for using FPU and TMU on F2800132.
