How to limit the slope of a signal

[yingxiong10]

Hi,

   I am trying to limit the slope of my speed control reference signal, say I want to change from 100rpm to 200rpm, I don't want it to step from 100 to 200 (which is what the code is doing now), I hope it can change gradually with a changeable slope. Could anyone help me on this ? Thank you very much.

There are many ways to do this, here is one possibility.

Thank you for your reply. But I can't open your file since I am using a labview 14.0.2. Could you do a screen shot maybe for your diagram?

Hi ying,

see "PID Output Rate Limiter" function…

(Despite its name you can also use it for input signals! :D)
