In this paper a method is presented for the design of an indirect
adaptive fault-tolerant flight control system for accommodation
of multiple control effect or failures. The method is based on a
convenient parameterization of the failures and suitable representation
of the overall system. Such a representation and a control law with
adjustable parameters yield an error model similar to that encountered
in standard adaptive control. Based on a suitably chosen adaptive
observer, it was shown that the corresponding adaptive laws result in
a globally bounded closen-loop system in which asymptotic convergence
of the output errors to zero is guaranteed.
