Hi

I tried PMSM FOC with attach file

So, I need kindly mention of Configuration S12ZVM_PMSMFOC_appcfonfig.xls

Specially, Please look below Picture

i did attach project file

Original Attachment has been moved to: MTRCKTSPNZVM128-SW.exe.zip

Thank`s your Kindly mention .!

Hi Ahn,

Could you please clarify what you mean by “mention of Configuration S12ZVM_PMSMFOC_appcfonfig.xls”?

Do you need to explain what does these calculators and constants? Or you need to check whether target values are OK?

Have a great day,
Radek

Hi Radeks

Thanks your interest my question

FOC Setup

Current loop sampling period

CLOOP_TS

100.0E-6

Current loop bandwidth

CFOC_F0

400

Current loop attenuation

CFOC_ATT

0.9

Q1 : What is mean “Current loop sampling period”

Q2 : What is mean “Current loop bandwidth”?

Q3 : What is mean “Current loop attenuation”?

Q4 How can I tuning upper Questions Value with Freemaster ?

Thank you kindly answer

Best Regards

Hi Joseph,

In normal run, the motor is driven by two closed loops.

The fast loop is executed typically every 100us and we call it the Current loop.

The slow loop is executed typically every 1ms and we call it the Speed loop.

The Current loop:

From Current loop bandwidth and Current loop attenuation parameters are recalculated PI regulators parameters.

The typical value for Current loop bandwidth is 200~250Hz and for Current loop attenuation it is 0.8~0.9.

For more details, please look at application note AN5135:

http://www.nxp.com/files/microcontrollers/doc/app_note/AN5135.pdf

or look at theory by searching something like “close loop feedback control”.

I hope it helps you.

Have a great day,
Radek
