NI Robotic starter Kit DANI PID control

Hello

 

I have this great kit and interested to do a kind of research of PID control on the two DC motors.

I already saw links that can do this job but I noticed that I can not find any technical datasheet having the motor paramters ( Mechanical or electrical)
.

 

I plan to bulid a tranfser function usig these paramters and then design a PID controller to make a speed control.

 

I searched the internet for the datasheet for these motors and could not find.

 

I think I should use a system identification for these parameters...so the question is

 

Is it possible to do any experimental system identification for identification of the DC motor parameters without deassebling them from the kit???

 

and how to do this job using labview??

 

if any has the datasheets for these motors (TETRIX DC Drive motor, part number 39083) it will be helpful  ...

 

Thanks

Hi A Hakim,

 

Looking through our specifications for this kit it looks like there are 3 pieces of information given for the DC motors, they are located on this page > http://sine.ni.com/ds/app/doc/p/id/ds-217/lang/en#header2 

 

Will those parameters work for you, or were you looking for something else?

Hello ShishKeBobby

 

Thanks for your reply, but realy these information I knew, I need more information like a datasheet for this DC motors concerning the electrical and mechanical parameters.

 

I searched for the tetrix DC drive motor, part no. 39083 on pitisco web site but I could not download the datasheet.

 

these are the information I need

 

  1. Motor constants (KT, KE)
  2. Motor internal resistance (Rm) and inductance (La)
  3. Motor friction (viscous friction)
  4. Interia (J)

 

, thanks 

 

or I am thinking to get these parameters by system identification but I dont know how without disasseblying of the dc motor from DANI and having a benifet from Labview and the assembled Morors in DANI.....

 

what you think?

 

Thanks for help

Hi A.Hakim,

 

The information I've found for the motors is limited to what I've pointed you to (voltage, max torque and RPMs), which you already know.  In regards to the other information you've requested, I would suggest you contact Pitsco directly for component specific information.  I would advice holding off on disassembling the motors to test them yourself until you hear back from Pitsco as that sounds like a fairly non-trivial process to complete (unless I'm mistaken, feel free to correct me).

Hello ShishKeBobby

 

Thanks for your reply, Really I have already contacted PITSCO in parallel, but still they did not give me a reply..

 

Concerning the dissassembly, yes I'm holding off and waiting for their reply

thanks
