LAUNCHXL-F28379D: Sensorless foc for HVAC 3phase induction

Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE, SYSCONFIG, TMDXIDDK379D

Hi,

Im trying to use Launchxl-f28379d board to implement a High voltage sensorless DC-AC 3 phase inverter to control an induction motor. I already found an great TI example which is done for F2833x cpu but it's not compatible with 28379d. I wanted to know is there any shotcut or instruction to do necessary modifications to have atleast the initial pwm waves. This is the exact thing I want to implement which is done for f2833:

https://www.ti.com/lit/pdf/sprabq0?keyMatch=SENSORLESS%20FOC%203PHASE

I wanted to know is there any shotcut or instruction to do necessary modifications to make it compatible to 28379d? In this project all of header files and peripheral configurations are dependent with f2833, so it's very hard to change every details.

Every suggestions are welcomed.

Appreciate your help

Sorry, there is no any document and reference example to show how to migrate the ACIM example to F28379D as you want, you have to do this by yourself.

You can find the example with F2833x in controlSUITE as below, and you just need to change the device configuration codes in the related files like "HVACI_Sensorless-DevInit_F2833x.c".

C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVACI_Sensorless

C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVACI_Sensorless_2833x

Thank you for reply.
I am working on the same code you shared the link. the problem is all header files, pin configuration and basically everything except the macros and functions need to be changed which is like doing the project from scratch. Please tell me if I am wrong about this.

Yes, you have to change the codes related to the device in the files except the MACRO functions for motor control algorithm.

I understand. So there is not an "easy way" or shortcut to do that as far as I understood.

One problem is that there is no driver for F28379d in this path:
C:\ti\controlSUITE\libs\app_libs\motor_control\drivers
does it means it can not support the motor control libraries?

Thanks

You can find the device support codes for f2837xd in C2000Ware as below. You may refer to the examples here to change the codes as driver for f2837xd.

C2000Ware: https://www.ti.com/tool/C2000WARE

C:\ti\c2000\C2000Ware_<version>\device_support\f2837xd

Motor control libraries include driver and math block. The math block can support all of the C2000 controllers include F28379d.

I tried to do this but I couldn't make it. Apparently lots of epwm macros are incompatible with F2837xd epwm header file and I got too many errors.

I was curious if I can use sysconfig tool for this purpose to make it easier but the example I shared earlier doesn't have sysconfig file in its project.

Am I going to the right direction? If yes can you please help me to migrate this example project to be compatible with f28379d?

Yes, you can use the Sysconfig to generate the device configuration code, or write the device configuration code based on the driverlib examples in C2000Ware to replace the macro function of the driver library in the example project.

Or you can refer to the motor control example with F2837x in Motor Control SDK, and just need to migrate the motor control block for ACIM to replace the using motor control algorithm in Motor Control SDK.

Thank you for your reply.
Can you explain more about second option?
Which example you meant?
My application is 3 phase induction motor FOC sensorless, is it anything similar to that?

0 Yanming Luo over 2 years ago in reply to Hamid Zargaran

TI__Guru** 115420 points

There is no an example for the 3-phase induction motor with sensorless FOC in Motor Control SDK. You might have to implement the first way above.

Yeah I understood that. My question was about this part of your previous reply : "Or you can refer to the motor control example with F2837x in Motor Control SDK"
Can you name which motor control example?

0 Yanming Luo over 2 years ago in reply to Hamid Zargaran

Please download and install the Motor Control SDK

C2000WARE-MOTORCONTROL-SDK: http://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK

You can find a sensored-FOC for PMSM example at the folder below.

C:\ti\c2000\C2000Ware_MotorControl_SDK_<version>\solutions\tmdxiddk379d\f2837x

BTW, you may try to use the first way as mentioned above. The example in motor control SDK uses driverlib in C2000Ware that is totally different than the example in controlSUITE.
