Question

The response to a unit step input of a order system in closed loop control with proportional gain is shown to the right. All of the following questions can he answered by the characteristics of this response. The response with the largest pin setting is, ... The pcrcent overshoot of response C is most nearly. .. The steady stale error of response A is moist nearly, .. The settling time (in seconds) of response C is most nearly. ... Since response A is over-damped and appears 10 look like a 1 order response, it could be Since response A is overnJampcd. it could be approximated by a |- order response such as best value for coefficient t would be. ...

Explanation / Answer

A) The largest gain is on C graph as Y(t) is more in C part only.

B) Its 20 % because 1.1 - 0.9 = 0.2 gives 20%

C) 1 - 0.5 = 0.50

D) 2

E) 0.5

F) 3.0

g) 1- 0.75 = 0.25
