MyRio calculation time for RCP

[ajavadi]

Hi,

I'm a researcher in Power Electronics and I wish to know about the performance of the MyRIO.

We are currently using dSPACE (dsp1104) modules for our Rapid Control Prototyping. When we implement our control algorithm, we define a Time step in the MATLAB/Simulink environment. For example, we can not go less than 40us for a simple controller, otherwise we encounter a message of "OverRUN"

I wish to know what is the lowest Time step the MyRIO could achieve for a simple controller in a RCP loop.

thanks

Hi,

There is also not one single answer to your question since with a NI RIO platform (including NI myRIO) you have the choice to put your controller on real-time target and/or on the FPGA. NI myRIO has a 40MHz Onboard Clock putting a single FPGA tick at 25ns so also the size/complexity of your controller will define/impact the cycle time.

If your research is in power electronics you might also be interested in using the the NI Single-Board RIO General-Purpose Inverter Controller (GPIC).

Can you give me specifics about your location? I'd like to connect you to the right (technical) resource since I believe that your application/request probably deserves more then just a simple answer in this forum in order to explor all possibilities.
