TMS320F28027F: Are there any updated codes for ACIM V/F that can run motors smoothly without torque ripple effects?

Part Number: TMS320F28027F
Other Parts Discussed in Thread: CONTROLSUITE, MOTORWARE

Tool/software:

Hi everyone,

I am using TMS320F28027F V/F control, which is my favorite method since it does not require any motor identification. I am working with HVACI code, but unfortunately, it has torque ripple. I tried using correction dead time compensation to eliminate the torque ripple IT code is something like this : 

 value+= _IQmpy(_IQsat(Current, Ith, -Ith), Kdtc);  ,

the results got a bit better, but they were not as good as I expected. TI's (FOC) or in any industrial drives which we can find on the market even in V/F mode, there are no torque ripple effects. I want my motor to rotate as smooth as those ones, 

As far as I know, two years ago, I searched extensively for resources on C2000 V/F control to run motors without torque ripple, but I could not find any. are there any updated codes for ACIM V/F  that can run motors smoothly without torque ripple effects—similar to FOC in terms of smooth rotation?

Dave.

Thank you!

    No further update. The v/f control in motorWare is only for hardware validation. You can refer to the v/f control in controlSUITE.

I understand that you are busy, and my questions may not be highly advanced, but I would greatly appreciate any additional insights you can provide. If you are unable to assist further due to your schedule, please feel free to pass my question along to another TI expert.

    Thank you for your attention to this matter.

    Best regards,

    As mentioned above. If you want to implement v/f control for an ACIM, it's better to refer to the example lab in controlSUITE. The example project is not based on F28027F, but it could be easy to be ported to the F28027F. The example lab (lab01b) in motorWare is not a real v/f control.

    CONTROLSUITE  http://www.ti.com/tool/CONTROLSUITE

    V/f control for ACIM: C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVACI_Scalar

    If you want to achieve a good dynamic response to suppress the torque ripple, you may have to implement the FOC as shown in the motorWare like lab05~lab10a.
