Tasks: Perform the following tasks for Configuration 2 and Configuration 3. 1. Evaluate the transfer function of each subsystems (Potentiometer, Preamplifier, Motor and load Gears, and Potentiometer). Refer to the "Antenna Control: Transfer Function" case study for help (Chapter 2 pages 92-93). 2. Assume an open-loop system (feedback path disconnected) and do the following (Refer to the "Antenna Control: Open Loop Response" case study for help: Chapter 4 pages 202-205): a. 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. b. Find the damping ratio and natural frequency of the open-loop system. c. Derive the complete 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. d. 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.
