TIDA-010054: Analysing the contol loop

Hi Vincent,

Umin and Umax are saturation limits for the PI controller. In the case f the TIDA-010054 Lab 4 with closed current loop these are the phase shift limits in pu.
1pu = 360 degrees or 2pi rad.

Please find more information in the DCL User'S Guide:

Hi Andreas,

Thank you for the fast reply.

I have another question.

I am trying to make a parrallel PI structure. Is there a library to use an integrator in CCS?

Are is it possible for you to show me an exemple of integrator? I found exemple on the internet, but it look too simple...

Here error = setpoint - feedback;

There must be an integrator in (DCL_runPI_C6), can you explain it to me?

thank you for the great support,

Vincent Beaulieu-Gagnon

Hi Vincent,

Forwarding this to our C2000 experts.

Best regards,

Andreas

Hi Vincent,

DCL_runPI_C4 is a function for parallel PI structure. I do not think we have one only with integrator.

Thanks and regards, Pawan

Hi Pawan,

There is nothing for me in C4, it's going to externe.

Thank you,

Vincent Beaulieu-Gagnon

Vincent,

Did you try using our PI function with Kp=0? That would essentially serve as an integrator.

Thanks,

Sira

Hi Andreas,

I can't find the sampling frequency used for DAB_vSecSensed_pu. Can you help me find it?

thank you

Vincent Beaulieu-Gagnon

Hi Andreas,

So the sampling frequency is 100 kHz. I am trying to understand how it's done?

Here is the road i used. But i can't find the line that define the sampling frequency to 100 kHz.

Also what is (DAB_VPRIM_ADC_ACQPS_SYS_CLKS 40)?

thank you
