Adaptive Control For Time Delay Systems Applied To Flight Control

This paper presents an application of the Adaptive Posicast Controller (APC) to ight control. The APC is an adaptive controller with explicit delay compensation built upon the ideas of the classical Smith Predictor, nite spectrum assignment (FSA) and adaptive control. Simulation results are reported where APC is applied to control the longitudinal dynamics of a jet transport aircraft. These results demonstrate improved performance compared to conventional model reference adaptive controller (MRAC) and eective handling of time delays and uncertainties.
