Assuming the system is linear, time-invariant, and minimum-phase (no RHP zeros or poles), make an estimate of the open-loop transfer function of the motor-load system, i.e., determine the analytical transfer function that best represents the experimental data. Show all your steps. Explain Bodes Gain-Phase Relationship. Apply it here to verify the phase angle vs. log10 plot that accompanies your dB vs. log10 plot.
