Unformatted text preview: ECE 147B W2011 MOD7 Solution 1. The first problem considers two additional designs of the satellite dish network introduced in the module. Design (1) is to have relatively aggressive pole locations, and design (2) is to have significantly more sedate locations. The pole locations for design (1) should be fairly close to the origin, and a valid choice would be z=0 and z=0.02. Figure (a) shows the response of the angle plotted over the control input. As expected, the angle of the satellite stays very close to the origin even in the presence of the wind signal. Figure (b) below shows the actuator effort plotted against the wind signal for the first 10 seconds of the simulation. As expected, the controller works in the opposite direction as the wind is pushing to align the satellite. Design (2) must have poles far away from the origin, and one example of a valid choice is z=0.7 and z=0.9. Figure (c ) shows the response of the angle plotted against the control output. Here we see that the angle has a minor oscillation on the presence of the wind, and since the controller is not as...
