evealed that the damping spec was taking points off of the plot improperly. This is illustrated by the support plot shown below. Figure 66 – A problem with the damping spec The damping ratio spec looks for local maximum and minimums and assumes they define the envelope of decay. When a high frequency oscillation is superimposed on a dominant lower frequency, the points picked for the damping ratio calculation are no longer valid. In the case of the response of Figure 66, the invalid point resulted in a period that was less than half of the actual value. The resulting point plotted on the spec was on the imaginary axis, at a value of approximately 8rad/s. Since this high frequency oscillation always occurred immediately after the initial peak, a restriction was put on the selection of the points such that the period had to be larger than 4 seconds, or the point would not be used. This time gave a sufficient buffer to ensure that no invalid points were used. After the modification was made, the spec was able to return accurate results. Once again, the batch problem was run, but this time with more success. A second gain schedule was created for the new results, shown in Figure 67. 111
Figure 67 - Corrected gain schedule This gain schedule shows a large improvement over the original plot. <strong>For</strong> the most part, all four design parameter schedules are mostly smooth, and all four can be seen to follow an identifiable path. 112
