Yet another demonstration for my students.

Some parts are commented in Polish. Sorry for that :) For more details please consult -- also in Polish :) This submission contains two EKFs: one that assumes no knowledge of the moment of inertia and another one that can be applied if the moment of inertia is known.

thank you, thank you ,thank you .
and can i ask a question , i want to apply the EKF to the PMSM can you help me with that . i just want an article or any thing that could help me to build a model step by step and in easy way
again thank you

Dear Jone Liu,
Please google extended Kalman filter induction motor drive - plenty of edu resources out there.
For Polish-speaking students: .
Best regards,

Jone Liu

Dear Bartlomiej Ufnalski,

Thanks a lot for sharing your great work.

Just wonder if there are any related publications which can help our understanding of the examples.

Best Regards,
Jone Liu

Dear Guo Zhuoyu,
You're perfectly right. However, my intention here is not to provide a fully functional all-in-one model. Some work has to be left to my students :) You can use S-Function to incorporate the included EKF code into your Simulink model.
Best regards,

EKF is an observer, the output of the EKF should be the input of the controller. But actually your EKF and the whole system is separate.



Modeling of the system noise corrected. A huge thanks goes to my colleague Arkadiusz Kaszewski for pointing this out.
