Q3 A magnetic disk drive requires a motor to position a read/write head over tracks of data on a spinning disk. The motor and head may be represented by the transfer function: 10 G(s) s(ts + 1) Where t = 0.001 second. The controller takes the difference of the actual and desired positions and generates an error. This error is multiplied by an amplifier K. (1). Evaluate the steady-state position error for a step change in the desired input; (ii). Estimate the required K in order to yield a steady-state error of 0.1 mm for a ramp input of 10 cm/s.
