I am working on the project of "sensorless speed control of a BLDC motor using TMS320LF2407"

I am facing problem with the transfer function of BLDc motors.

If someone has the information about the PI controller for the same, i will appreciate that too.

Thanks, Manish

I have a document that gives the transfer function of a BLDC motor and a DC motor. I also have a document that shows how to implement PI compensation in an electric servo. I can email these documents to you if you would like to have copies. Just give me your email address.

I'd be surprised if you can't find application notes in TI's database on the subject of sensorless control.
If you were not successful, try motorola, they have good app notes on subject of motor control.
Of course, they based it around thier dsp.

No single transfer function for 6-step commutated brushless motor - it is rather variable structure system. See more explanations along with some sensorless stuff at

Hi George,

I am interested in your documents, my email address is

Why are u worried abt the TF?? Go for a Fuzzy logic based control. For advanced research u can even try Neural net with a fuzzy controller, adaptive control!!

 

I also work on this project,so,if u want to we can exchange our knowledge.

I have a paper on the transfer function of DC and BLDC motors. You may have
it if you will give me you email address.

George,

I am working on digital control of BLDC motors. I am also interested in the document on transfer function of DC and BLDC motors. I request you to send the above document to me.

My email id is [email protected]

Thanks in advance,

G. Mohan

 

Can you please send the Technical paper giving BLDC transfer fucnction to this e-mail id?

I have to control a bldc motor via Pid or Pi and i have problem with simulink model as well. Can anyone help me about this?

 

Hi George,

Could you please send me these documents. I'm also working on BLDC motor control (with sensor). I'm new & I'm writing drivers to control the movement of hte motor. My address is gautham_g [at] yahoo [dot] com

Thanx
Gautham

 

Hi,

Hi George
Please ,I requested your BLDC documents since time ago but until now I didn't receive them.
Please, if you don't minde send me your documents
and thank you very much for your help.my email is: [email protected]
