Refer to the antenna azimuth position control system shown in Appendix A2, Configuration 2. Assume an open-loop system (feedback path disconnected) and do the following: 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 op loop system. c. Derive the open-loop angular velocity response of the power amplifier, motor, and load to a step-voltage input using transfer functions. d. e. State Space Obtain the open-loop state and output SS equations. MATLAB ML angular velocity response to a step-voltage input. Use MATLAB to obtain a plot of the open-loop
