the actual aircraft as a baseline then modified the architecture to improve the handlingqualities optimizing the gains using CONDUIT after each modification. Dozens ofconfigurations were tested before the final architecture was achieved.The pictures to code model of the SH-2f was used by the researcher to confirmthe control behavior and to observe the degradation of the control laws as the trimcondition moved away from the baseline used to generate the control system gains.X-29A - Pitch axis only, StateSpace, Fixed Wing Model WithFeedbackThe first aircraft model usedwas a thesis project completed at theNASA Ames research center by MarkMorel. The aircraft model is averified pitch axis only state spacemodel of the X-29A (figure 25.)provided by NASA Dryden researchFigure 25 NASA X-29Acenter with a quickness pre-filter added to the original control system to improve thehandling qualities. After adding the quickness filter, the system gains were optimizedusing the CONDUIT software. The trim speed of the model is 726 feet/second.Modifications Required to FlyThe Simulink model of the X-29a contains outputs for: Forward velocity (bodyaxis), alpha (angle of attack), q (pitch rate), theta (pitch angle world coordinates), Nz(g s), stick actuator rate, flap actuator rate, and canard actuator rate. The outputs from thestate space are all perturbations from a steady state. An example is that even though thetrim speed of the model is 726 feet/second, if the speed output from the state space is fed69
