Other Parts Discussed in Thread: CONTROLSUITE

Hi all,

I'm proud to be here,

I am student from Hanoi University of Science and technology of Vietnam,

My field focus on Motor Drive for all electric motor,

This term I have one project about BLDC Sensorless Control,

and I just success on simulation Speed drive control use 2 PI controller for Speed and Current,

I need some demo example from you guys - my friends, sensorless control for BLDC motor, - using any techinique,

base on probably BEMF or flux linkage on Simulink software, any technique it good for my project,

I really appreciate any help form you guys, all contact please contact me at:

toankspm@gmail.com

I never forgot your help,

Thank you,

Toan.

Hi Toan,

What type of motor are you trying to drive(Wattage, BLDC, sinusoidal, Trapezoidal) and what voltage level are you wanting to use to drive the motor?

Regards,
Michael

HI Michael,

thanks for your response,

as I mentioned, I control BLDC using sensorless technique, and the rate voltage is 48V,

Before I do experiment about sensorless BLDC project, I need to simulation systems on Simulink Software,

So what I need is your example simulation on Simulink software of whatever software you test your design BEFORE you do experiment,

TOday, I success on simulation Speed COntrol Drive using 2 control loop:
+ one is Speed: PI control
+ two is Current: hyteresis control
But still using Hall sensor to detect position rotor,

Next, I need to simulation without Hall sensor, using technich to estimate Back-EMF and therefore speed estimate,
if you do this, please send me some ideals,
I appreciate your help,
Thanks,
Toan.

Hi Toan,

I am sorry, we do not have any Simulink models of our motor drive devices.

Hi Michael,

Don't get me wrong,

I try to do experiment this project: for sensorless control algorithm,
But before that, I need to succees on simulation on Simulink, this is my activities of my laboratory work

and 5 days ago, I done simulation for 2 controller control: speed and current using Hall sensor to detect rotor position.

and today I keep simulation on sensorless control, that why I ask you some ideal, but it not kind of issu, I keep simulation untill done.
after that, I do experiment on C2000 microprocessor.

I need your help until I done simulation,
Thank you,
Toan

Hi Toan,
Sorry, We do not use Simulink for our simulations so we do not have any simulations of motor controls for simulink either.

Regards,

Hi Michael,

I would take continue my project,

after a few days, I done simulation Sensosless control for BLDC Motor using 1 observer, I follow 1 paper on IEEE source, this link on gg scholar,

So, afterward, I want to do this project on TI microprocessor,

So can you tell me if TI Company can support me- like a student cant not afford to many thing like: motor, micro processor, inverter, ...

So please tell what I need to do if TI support me some hardware and software?

Thank you for your help,
Toan.
