If you are looking for 6 step trapezoidal control and FOC, we don't have that example.

FOC typically produces sinusoidal current waveforms. Such examples available in controlsuite at

C:\ti\controlSUITE\development_kits\TIDM-SERVO-LAUNCHXS

This example is on F28377 Launchpad that we discontinued, but this can be ported to F28379D platform by the user. The entire source code is available for user edits.

Another example is available using FCL (fast current loop), where part of the algorithm is available as .lib, at

C:\ti\controlSUITE\libs\app_libs\motor_control\libs\FCL_SFRA\v01_00_00_00

This example is on F28379D Launchpad. The advantage with FCL is the high current loop bandwidth..

I want am example using texas supported package blocks

Using simulink and the supported blocks , i haven't found any example using sensors in foc , all the examples here and on mathworks are sensorless

Can you pls verify my previous post, I have given the location where you can find what we offer on sensored foc. If that does not meet your requirements, then we have nothing else to refer. Thanks.

Hi Omar,

In our shipping PMSM FOC example, we show both sensored and sensorless approach. This example is for F28069, but you can update to F28379D as needed.

Example model c28069pmsmfoc_ert has Hall sensor based and sensorless implementation. You can select the approach in the model using a switch block.

Cheers,

-Brian

it is very useful example but there are some blocks that I can't understand in this example. where I could find a detailed explanation for this example?

Other then the documentation (which covers every block), there might be some links in this post which can help explain. I don't know of a detailed explanation of that specific demo.

Cheers,

If i want to see the output time stamps of capture events on osciliscope to ensure that i have understood it how can i make it. When i use digital output it gives me an error port width dimension ecap is one dimensional vector with two elements

Omar,
Wanted to check back with you to see if this was still an open issue, or if we need to start a new thread etc.

Best regards,
Matthew
