Abstract
This paper presents preliminary results of the application of the Parameter Space Investigation
method for the design of the L1 flight control system implemented on the
two turbine-powered dynamically-scaled GTM AirSTAR aircraft. In particular, the study
addresses the construction of the feasible solution set and the improvement of a nominal
prototype design, obtained using the systematic design procedures of the L1 adaptive
control theory. On the one hand, the results in the paper demonstrate the benefits of
L1 adaptive control as a verifiable robust adaptive control architecture by validating the
theoretical claims in terms of robustness and performance, as well as illustrating its systematic
design procedures. On the other hand, the paper confirms the suitability of the
Parameter Space Investigation method for the multicriteria design optimization of a flight
control system subject to desired control specifications. Also, in order to facilitate the multicriteria
analysis process, this study takes advantage of the Multicriteria Optimization and
Vector Identification software package, which was designed to apply the Parameter Space
Investigation method to engineering problems. The results and conclusions of this paper
have contributed to the improvement of the (predicted) flying qualities and the robustness
margins of the all-adaptive L1-augmented GTM AirSTAR aircraft.
