TMS320F28069F: InstaSPIN Projects Lab 5h

Part Number: TMS320F28069F

Hello,

I have a question on InstaSPIN Projects and Labs User's Guide.

Specifically it is on Lab 5h - Step Response Generation & Graphing for Controller Tuning.

It is mentioned in its Abstract that in some motors Ls may be difficult to identify.

My questions are as follow.

1. Would you please explain me in more detail with respect to the motors where Ls may be difficult to identify?

2. Why are some motors difficult to identify its Ls?

3. What should we do when Ls is difficult to identify for a motor?

Thank you for your guidance.

With regards,

JS Yoo
