Consider a second order system = 2 2+ 2+ 2 . using matlab simulink, plot the step response for the following scenarios. is the system underdamped, overdamped or critically damped in each case?

a) = 0.5, = 1
b) = 0.5, = 2
c) = 1, = 1
d) = 2, = 1

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer is  

a.

p = 78

step-by-step explanation:

i'm pretty sure the answer is a. decreases with increase in
