Hi there ...i have a problem with implementing adaptive control using labview 8.5 to control the DCMCT Qnet motor

i opened new disscusion plz have a look

It would be super helpful if you could post your code.

Hi,

here is my code  and as i mentioned im using DCMCT qnet motor with labview 8.5

the problem is connecting ARX system identification method to adaptive method and be able to find the PID gains from the Transfer function.

thank you for your help.

Hello Aswwa,

Could you also include the subVIs that you used in your main VI?

Hi,

here is the project .

sorry abput the above project ....

this one is the complete one

It seems that you are trying to pass single points into ARX and that it probably needs an actual array of points or a waveform. Are the array stimulus and response signals the only inputs you have questions about? I take it the output model it creates doesn't look right to you either? I am not an expert on this and will need to talk to someone else and post back.

yes that is one problem and how can i get the PID gain for my controller from the estimated transfer function

thanx alot for your help

Hi,

I'm not sure what you want to accomplish with ARX sys id. You already defined, with matrix controls A,B,C and D, the transfer function that you are trying to identify. Only one value for stimulus and response is not consistent with ARX and also conversion from ARX model to TF is done with SI Model Conversion.vi

hi,

im tring to adapte anychanges in the system and A,B,C,D are initial model of system
