Hi dear Yanming,
Thank you for your kind quick response.
Previoulsy i worked on the related document you refer.
However, i look for the documents which contain mathematical implementeation or expression for eSMO such as the document in MotorControl for SMO.
Actually, i could not find theoratical document for eSMO.
I look for your further direction.
Regards,
Sami

eSMO is the SMO plus PLL.

Hi dear Yanming,
This document is also lack for theory.
I use TMDXIDDK379D, but i could not do anything to improve SMO model to eSMO.
How can i get the open-source code and theoratical documents of eSMO.lib
Regards,

Sami

No additional document of the eSMO.lib as you want. The document mentioned above includes a very detailed technical background about SMO and eSMO, the open source is also included in the motor control SDK.
