Investigate the effects of increasing motor inertia on inertial-reduction instability using Experiment 16B.

Tune the system setting the motor inertia to the following four values: 0.0018, 0.0045, 0.009, and 0.018 kg-m². Using the step response for tuning systems subject to inertial-reduction instability is difficult, so use closed-loop Bode plots. In each of the four cases, maximize KVP with the gain above the antiresonant frequency remaining below 0 dB. For simplicity, leave K_VI at zero for all cases. Record the following: motor inertia, load/motor inertia ratio, KVP, and bandwidth. Note that the bandwidth is the lowest frequency where the gain falls to - 3 dB. What conclusions would you draw?
