TMS320F28379D: FCL(Fast Current Loop) for absolute encoder

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Dear Motor Control Team,

I'm developing an actuator using CSMA_04BT1ANT3 servo motor ( t-format 23bit absolute encoder, 220V/400 Watt ) and TMS320F28379D based Motor Driver.

Thanks to TMS320F28379D and t-format library, encoder interface is working well, and currently I'm tuning gains of controller.

I would like to apply the FCL to my actuator to improve performance, but I can't find an officially published library, so I inquire about the publication schedule.

If you do not plan to publish for the time being ,by refering "./HVMotorCtrl+PfcKit_v2.1/HVPM_Sensorless_CLA_F2803x" I'm going to moving current control loop to CLA.

How long is the difference in the execution speed of code written in C and asm for CLA?

Sincerely,

Eui-heon

Hello Eui-heon,

You can find FCL library in C2000Ware Motor Control Library. http://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK

FCL is in this folder : \C2000Ware_MotorControl_SDK_1_00_00_00\libraries\fcl

But I am not sure that FCL works with an absolute encoder. As far as I know, it only works with incremental encoder. Please have a look on this thread: https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/799334

Regards,

Hakan

Dear Team,

I would like to ask if you plan to publish an FCL for an absolute encoder. If so, when do you think it will be?

Sincerely,

Eui-heon

It is in our to do list, hoping it after 3-6 months.
