Hi techs! I've created a Ball & Beam model on MotionView to explore a co-simulation with Activate.

 

Many of you may have seen this on undergraduate/master class studying on frequency or even on time domain. I've decided to do something different, creating the model on a multibody environment. :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

 

The control is a simple PD, where I've calculated using analytical method (Kp +Kd.s) with a specified overshoot and settling time. You could explore changing its values...

I'd like to thank @Livio Mariano for suggesting me his own low-pass filter :D/emoticons/default_biggrin.png' srcset='/emoticons/biggrin@2x.png 2x' title=':D' width='20' /> in a way to filter the input displacement signal (without it I was having a problem to converge).

 

I've created a short video to show you how it works, and the files are attached. Enjoy! ;)/emoticons/default_wink.png' srcset='/emoticons/wink@2x.png 2x' title=';)' width='20' />
