problem with prject

[alameer]

welcome

i doing projet as shown below

by using DAQ & LV 8 and use PWM

i take signal from DAQ which refer to voltage which converted to Actual theta (Numirc .

this theta must be compered with desired Theta with Actua

1- if Acutal theta greter than Desierd theta must be decrese the PWM 1.

2-if Acutal theta less than Desierd theta must be increse the PWM 1

3- if Acutal theta equal Desierd theta must be outputing this signal by PWM

here my try , here iam SubVI PWM as shown

but i, can't found any result !!!

summry :

how i can get the desired theta by using PWM ?

i need help

thanks

Hello Alameer,

First forget the dynamic data type, you never use it in your code. Have the Daq assistent put out a Voltage (or better the theta, but that is another exercise).

Then probe what theta comes out, is that correct?

Another tip, use executed highlighting.
