TMS320F28069F: InstaSPIN-FOC Lab projects: Rs Online Recalibration functions in Lab 7 and Lab 11a

You might take a look at the instaspin lab guide, these two labs use different project structures. 

The EST_setRsOnLineAngleDelta_pu() is called in the CTRL_setEstParams() in lab07. The CTRL_setEstParams() is stored in ROM with FAST library.

Hello Yanming Luo,

Thank you for your review.

I have found out that the CTRL_setEstParams() is called at the end of CTRL_setParams().

Meawhile, in Lab07, the CTRL_setParams() is only called at the initialization section of main().

It seems that the CTRL_setEstParams() is not called anymore when the motor is running.

Am I correct?

Thank you for your guidance.

Correct. It's just for setting the estimator parameters during initialization.

Hello Yanming Luo,

Thank you for your review.

What I am asking you is that, while the motor is running, the updateRsOnLine() in Lab 11a periodically calls the EST_setRsOnLineAngleDelta_pu() in the background loop whereas the runRsOnLine() in Lab 7 never calls the EST_setRsOnLineAngleDelta_pu() in the background loop.

Therefore I suppose that the performance of the updateRsOnLine() in Lab 11a might be different from that of the runRsOnLine() in Lab 7.

How do you think?

Thank you for your guidance.

This function doesn't need to be called in the background loop, you might ignore it since the arguments are fixed values for a motor.

Hi Yanming Luo,

Thank you for your review.

I suppose that I might understand what you mean.

I assume that the performances of both updateRsOnLine() in Lab11a and runRsOnLine() in Lab7 are exactly the same because the arguments of the EST_setRsOnLineAngleDelta_pu() are fixed values for a motor.

Is this what you mean?

Thank you for your guidance.

With regards,

JS Yoo
