31 A first-order system has a time constant of 30 s. What will be its
delay time and rise time when subject to a unit step input?
32 A first-order system when subject to a unit step input rises to 90% of
its steady-state value in 20 s. Determine its time constant, delay time
and rise time?
33 Determine the natural angular frequency, the damping factor, the
rise time, percentage overshoot and 2% settling time for systems
with the following transfer functions: (a) 100/(s + 4s + 100), (b)
49/(s + 4s + 49).
34 Determine the natural angular frequency, the damping factor, the
rise time, percentage overshoot and 2% settling time for a system
where the output y is related to the input x by the differential
equation:
쫓+5%+16y= 16x
