Large microwave antennas have become increasingly important for radio astronomy and satellite tracking. A large antenna with a diameter of 60 ft, for example, is susceptible to large wind gust torques. A proposed antenna is required to have an error of less than 0.10° in a 35 mph wind. Experiments show that this wind force exerts a maximum disturbance at the antenna of 200,000 ft lb at 35 mph, or the equivalent to 10 volts at the input Td(s) to the amplidyne. One problem of driving large antennas is the form of the system transfer function that possesses a structural resonance. The antenna servosystem is shown in the figure below. The transfer function of the antenna, drive motor, and amplidyne is approximated by R(s) where G(s) = Power amplifier G₁(s) T/(s) Sensor k,= 1 Antenna, drive motor, and amplidyne G(s) w/1 s(s² + 25w,s + w²/1) 0(s) Position (radians) where zeta = 0.707 and wn = 15. The transfer function of the power amplifier is approximately
