A new servo block "Beta" has been added after detecting the velocity. It feedbacks just before "Fv/m". You can change the value of elements by double-clicking. If this applet looks something weird, please reload it. You can see Beta = 6.0e-4 by double-clicking. As the block diagram says, "BetaFv/m" is parallel for "C/m". (C+BetaFv)/m is much bigger than "C/m". The feedback makes damping factor bigger and decreases the resonance. If you choose "Step-Res", you can see how the pickup follows the "step" displacement. It looks stable but still takes time because the system is stable too much. Quiz 3 For actual implementation, it's impossible to detect the velocity of pickup. How do you get it?? Here is the answer.
