a) A control engineer has modelled the suspension system of a new model car using a 2nd order differential
equation. Using Laplace Transform, the engineer has managed to work out the transfer function, which is given
below:
0.001
s2 + 12s+81
What is the natural frequency, the damping ratio and the constant K of the system? Please show all calculations.
b) The same engineer has studied the suspension system of a SUV vehicle and modelled it using again a 2nd order
differential equation, which has resulted into the following 2nd order transfer function:
Y(s)
32
U(s) 4s² +8s + 16
For this system first calculate the damping ratio and its natural frequency and state whether the system is
underdamped, overdamped or critically damped. Then calculate the peak time, peak value, settling time and
damped natural frequency of the system.
