CCS/TMS320F28069M: No Schematic: Lab 11 – Without Controller Module - No Schematic

Part Number: TMS320F28069M
Other Parts Discussed in Thread: MOTORWARE

Tool/software: Code Composer Studio

There is no schematic associated with Lab 11.  It would be useful to compare to previous labs 1 through 5, although I think it's just going to be the same FOC diagram without the ctrl wrapped around it.

  • Please refer to InstaSPIN lab guide, it used the same control algorithm and block diagram as lab1~lab10, just move all FOC modules to mainISR without using ctrl_RUN().
  • The block diagrams between labs 1 and 10 vary widely.  Especially lab 1 which does not have a FAST observer, and is more of an open loop system.

  • The FOC diagram remains the same. For instance, in the block diagram given for lab5a, the FOC in lab11 remains the same but the individual blocks that fall under "CTRL_run" and "CTRL_setup" are instead broken out into their own respective API calls in mainISR() instead of being blanket executed by calling CTRL_run(). You could trace the diagram from HAL_readAdcData() through to HAL_writePwmData() by stepping through the code in mainISR() and extrapolating some of the details (such as all the API that go into the PI control loops for Iq/Id control)

  •  OK, 

    I will take your advice.  I found the diagram that explains graphically the issue we are discussing in the instaspin_labs.pdf, labeled  Version 1.0.11, Revision History: 1.0.12, Jan 22, 2015.  These figures occur on page 238 and 239, Figures 72 and 73.  I think this was associated with Motorware 14?  Anyways, this is a very hard subject (for me) and it gets frustrating sometimes.  Thanks for your help
