CP8.8 Consider the problem of controlling an inverted pendulum on a moving base, as shown in Figure CP8.8(a). The transfer function of the system is:
-1/ML
s^2 - (M + Mg)/(ML)
The design objective is to balance the pendulum (i.e., in the presence of disturbance inputs). A block diagram representation of the system is depicted in Figure CP8.8b. Let M = 10 kg, Mh = 100 kg, L = 1m, g = 9.81 m/s^2, a = 5, and b = 10.
