For a band pass system with unit step input. (See attachment for equations.)
For a CD player, a step force of 2N must result in a head velocity error of not more than...(See attachment for details.)
For a CD player, step in force of 2N results in head velocity error of not more than 1.0E-03 m/sec.
Input Disturbance = Di(s) = 2U(t) ... UNit Step of height 2
Ypeak = Yp = 1.0E-03 = 0.001
Plant = P(s) = 1/(0.03s+2) = 33.33/(s+66.67)
Damping coefficient = p = 0.7
