Consider the transfer function of a 2nd order system given by: G₁(s) = a/(s² + bs + k) where a, b, and k are tunable/choosable positive real constants. (a) We would like that the unit step response of this system reaches steady state in 0.5 seconds (i.e., the 2% settling time is 0.5 second) with an overshoot of 10%. Moreover, we would like that the system is at 0.75 in steady state. What are the values of a, b, and k that satisfy these characteristics? (b) If we were to double the value of k found from the previous step, how would settling time, overshoot, and final value of the system change? Please show/calculate.

G₁(s) = a/(s² + bs + k)
where a, b, and kare tunable/choosable positive real constants.
(a) We would like that the unit step response of this system reaches steady state in 0.5
seconds (i.e., the 2% settling time is 0.5 second) with an overshoot of 10%. Moreover, we
would like that the system is at 0.75 in steady state. What are the values of a, b, and k
that satisfy these characteristics?
(b) If we were to double the value of k found from the previous step, how would settling
time, overshoot, and final value of the system change? Please show/calculate.
