Abstract : An adaptive control scheme may provide the best approach to the problem of accommodating automatic flight control systems to the variations of dynamic characteristics encountered over the flight envelope of the aircraft. The C*-Criterion for aircraft time response provides a basis for the design of such a system. To provide a margin of safety, all control systems have redundant channels for emergency use. An adaptive control system can be designed to be self-organizing, and in such a configuration can provide its own failure monitoring, resulting in a simpler and more efficient system. This study shows that such a system is feasible, that the response of the system is within the limits set forth in the C*-Criterion, and that the self-organizing characteristics provide reliable operation over the whole range of flight operations.
