Exercise 1
For a control system with negative feedback, presented in Fig. 1, prove intu- itively, that step change in the input will allow the system to obtain steady state.

Hint: assume that G(s)disturb = 1, G(s)actuator = 1, G(s)process = kprocess, G(s)sensor = 1, G(s)controller = kcontroller, kprocess = const ∈ R, kcontroller = const ∈ R.
