Question:
Consider the antenna control system of Fig. P5.3-15. The units of the antenna angle θ(t) is degrees, and the range is ±45° .
(a) The input signalr (k) is generated in the computer. Find the required values of
r(k) to command the satellite attitude angle θ(t) to be 30° and to be −30° .
(b) Let Gp(s) = 20 / (s2 + 6s) , the transfer function of the motor, gears, and pedestal. Find the system transfer function as a function of the transfer functions D(z), K , and so on.
(c) Evaluate the system transfer function for D(z) = 1 , T = 0.05 s, and K = 20 .
