N2 - In this paper we apply retrospective cost adaptive control (RCAC) to the NASA Generic Transport Model (GTM). The goal is to demonstrate command following and disturbance rejection techniques using a minimum amount of modeling information. In previous work, RCAC was applied to GTM using knowledge of the nonminmum-phase zeros, the relative degree, and the first non-zero Markov parameter associated with the linearized flight dynamics. In this paper, we further reduce the modeling requirements of RCAC by demonstrating that only a limited number of Markov parameters are needed to control the GTM model. We first demonstrate the method on illustrative single-input, single-output (SISO) and multi-input, multi-output (MIMO) problems. Next we demonstrate the method on linearized SISO and MIMO GTM models, and finally, the fully nonlinear GTM model.
