Hello.

I have a question to technical support from TI.

I donwload manual  sprabj2.pdf(spruho5.pdf like).

And I can see intersting picture on page 5.VisSim show diagramm. 

Using module decoupling d and componen,protect saturated d out regulator and other module.

I can not to find describe this module in site TI(DMC librari and control suite).

Same describe have got freescale,but hav not got TI.

May be this information is confidential?

Dmitry

Please send me email dsp1108@mail.ru or answere there.

    Please review the InstaSPIN-FOC solution and the UG (SPRUHJ1), specifically ch. 12.8.  This solution is supported through MotorWare, not controlSUITE.

    The InstaSPIN-FOC solution includes voltage bus compensation derived from decoupling of the Iq and Id controllers.

    Ok Chris.

    I had problem with decoupling D and Q current.

    And writed about it before.I know about this document and write this:

    Can you produce soft modue to decouple D and Q or help creat.

    On VISSIM picture I saw soft module to decouple (it is ready to use) on the picture.

    But you write create this module alone without us...

    Now I design control module with tms320f28069F(or M index).

    Before I used TMS320F28335 an TMS320F28069

    For gubryd bus and electical bus(project was over good).

    In current project I would like to use INSTA SPIN option for calculate param AC motor.

    And use FOC control with sensor of speed.

    Hello Dmitri,

    I downloaded the document "SPRAPJ2.pdf", but I cannot find the VISSIM diagram you are referring to.

    I have developed d-q axis current decoupling blocks in the past, and have modeled them using VISSIM with good results.  Perhaps this is the source of the decoupling block image you are referring to.

    I have documented d-q current decoupling on my blog site in a tutorial series on how to properly design and tune PI control loops.  Specifically, I talk about decoupling in part 9 of the series:  http://e2e.ti.com/blogs_/b/motordrivecontrol/archive/2013/04/30/teaching-your-pi-controller-to-behave-part-ix.aspx

    Please be aware that InstaSPIN-FOC currently does NOT offer axis decoupling as an option.  You would need to add this feature in your own software.
