TMS320F28035: Back-EMF Observer method in Dave's slide

Jack Tan80

Dear C2000 Champs,

Dave Wilson in his motor training class show a method about how to observe back-emf, it seems that the simulation result is pretty good, so is there any related code that could be shared?

You should be able to find the simulations from Dave Wilson here: e2e.ti.com/.../m

Hi Sean,

Thanks for sharing the link with me.

I have another question, regarding to the low pass filter, what is the original model in s domain?

In my understanding, it should be LR circuit, the equivalent resistance in s domain should (sL + R), but whatever using forward rectangular rule, backward rectangular rule, and bilinear transformation, I can't get the exact model with Dave's simulation files, can you please help on this?
