Assume an open-loop system (feedback path disconnected) and do the following (Refer to the "Antenna Control: Open Loop Response"

  1. Predict the open-loop angular velocity response of the power amplifier, motor, and load to a step voltage at the input to the power amplifier.
  2. Find the damping ratio and natural frequency of the open-loop system.
  3. Derive the entire analytical expression for the open-loop angular velocity response of the load to a step-voltage input to the power amplifier, using the transfer function.
  4. Simulate the open-loop system's step response using MATLAB/Simulink. Calculate the corresponding time domain specifications, i.e., percent overshoot, time constant, rise time, settling time, and peak time.
