5.3-14. Consider the satellite control system of Fig. P5.3-14. The unit of the attitude angle (1) is degrees, and the range is 0 to 360°. The sensor gain is Hy = 0.05. (a) Suppose that the input ranges for available A/Ds are 0 to 10 V, 0 to 20 V, 0 to 30 V, £10 V, 20 V, and +30 V. Which range should be chosen? Why? (b) The input signal r(t) is a voltage. Find the required value of r(t) to command the satellite attitude angle (1) to be 80°. (c) Repeat parts (a) and (b) if the range of e(t) is 180° (d) Let Gp(s) = 1/(J5), the satellite transfer function. Find the system transfer function as a function of the transfer functions D(2), K, and so on. (e) Evaluate the system transfer function for D(z) = 1, T = 0.5 s, K = 4, and J = 0.2.
