Q12/ A second-order critically damped process has the transfer Function: Y(s)/U(s)= K/(Ts + 1)² (a) For a step change in input of magnitude M, what is the time (ts) required for this process to settle to within 5% of the total change in the output? (b) For K = 1 and a ramp change in input, u(t) = at, by what time period does y(t) lag behind u(t) once the output is changing linearly with time? %3D

Q12/ A second-order critically damped process has the transfer
Function: Y(s)/U(s)= K/(Ts + 1)²
(a) For a step change in input of magnitude M, what is the time (ts) required
for this process to settle to within 5% of the total change in the output?
(b) For K = 1 and a ramp change in input, u(t) = at, by what time period
does y(t) lag behind u(t) once the output is changing linearly with time?
