not able to work on a high frequency on RT target PXI 7831R

[gaura]

Hi all,

i have built a buck converter in matlab simulink and added iin veristand.

i am able to run it perfectly on RT target 7831R.

But as soon as i increase the frequency of the input i do not get the expected output.it runs fine only for low frequencies.

can anyone help me on the same?

should i change some parameters while building the DLL file?

the input given is external and i am observing the output on veristand.

Any advice will be of great help.

Hi gaura,

What rate did you build your model dll to run at? Ideal, you should be running your model at the same rate as what you had built the dll to run at.

What rate were you increasing the model rate to? And what exactly do you mean by unexpected output? How is it different from what you were expecing?

Cheers,

Olivia
