    Open loop state estimator ( Control theory-Observers)

    Hello guys i have a question. I want to simulate on simulink this example. and find the open loop responces from the real system and observer. On this examples says that we must use "strong u(t) to shake the things up" :P Does enyone know what kink of input is this? I use step responce and...
