TIMotorLIB (fast development of digital control systems)

Pablo Garcia

Hi,

I have developed a library I have called TIMotorLIB. The proposal of this library is to achieve fast development of digital control systems, mostly focused on the control of power converters, using Texas Instruments TMS320F28XXX Digital Signal Controllers (DSC) based boards. The development of this code has been done using the eZdsp F28335 board from Spectrum Digital.

The code provides a high level API to easily access all the functionality provide by the library. The modules being part of the library are:

Hardware related units:
- CPU clocking and interrupts:
- General purpose input output (GPIO)
- Analog to digital converter (ADC)
- Enhanced pulse width modulator (EPWM)
- Quadrature encoder peripheral (QEP)
- Serial communications interface (SCI)
- Memory data storage
Software related units:
- Complex numbers operations
- Motor control routines
- Digital signal processing routines

All the API is already documented, with several examples, and tested in many real applications, from mtoro control, sensorless operation and microgrids power converters.

My plan is to open the library under the LGPL license. As it is based on Texas Headers and it uses IQMath, I am not completly sure if that licence can be used.

Someone in the forum, preferely from TI, can ask to this

Regards,

Pablo

Dear Arefeee Mohammed,

people from TI just has contact me a couple of minutes ago. As soon as I have an answer about legal issues I will post here, at leat, the documentation. About the code, my idea is to upload it to a repositoty in Ti Forge or Sourceforge in order to open the development. I will keep you informed.

Regards,

Pablo

Hi all,

today I have make public the code of TIMotorLIB. It is located at:

https://gforge.ti.com/gf/project/timotorlib/

I hope the community will find this is useful. At least is being for me and my research team. Please, let me know any questions do you have.

Regards,

Pablo

Hi Pablo,

When I try to access the project I receive a permission denied... even as registered GForce user unfortunately

Best regards

Hi Pablo, I'd like how do you create that library. I cannot access to the files.

tanks.

Hi all,

It seems there is a problem with file permissions in gforge. I am now out of my office in a conference and do not have time to investigate that. As a temporary solution, I have put a copy of version 0.3 package in this direction

http://isa.uniovi.es/~pgarcia/TIMotorLIB/TIMotorLIB_v03.tar.gz

Let me know any problems you have.

Hi all,

TIMotorLIB project at:

https://gforge.ti.com/gf/project/timotorlib/

should now be open to everyone. Please, let me know any problems you have.
