TMS320F28377S: motor control

Part Number: TMS320F28377S
Other Parts Discussed in Thread: CONTROLSUITE

I'm studying about servo motor control using 28377 controller.

I can't understand the principle of SVGENDQ formula in svgen.h(controlSUITE, math_blocks, ver4.3)

So, I searched and found a document of DCS(Digital Control Systems) Group introduce SVGEN_DQ Transform.

however, that is older version doc and looks like ver 3.

There are some different part in source code.

please explain the formula to me. 

Thank you

    We dont have any additional doc other that what is already out in the controlsuite. It is a fairly old and established method and you should find some literature online.

    The implementation tries to identify the sector number and then do the pulse width calc. I suggest you to try this implementation in Matlab and analyze it. The equations are already given in C source and you may use that.
