real-time NI 9239

[shdkia]

Hi All,

I have a DAQ 9172  with two NI 9239 module. I would like to measure 3 stator current and 3 stator voltage and also the rotor speed (an analoge input) of an AC machine to estimate the electromagnetique torque in real time. The estimatior is an open loop one but it needs some feedbacks and also function transfer as I have used in Matlab Simulink. I have control and simulation and interface toolkit but not real-time toolkit. Please help me haw can I do that in real-time.

Hi,

The Cdaq-9172 are not a real-time controller, if you will use it in real time mode (with determinitic loop) you need have a computer with a real time OS.

Windows are not a real time OS, but you can optimize it with your application.

You can see below differents notes about real-time.
