Title

SNAC Convergence and Use in Adaptive Autopilot Design

Abstract

In this paper, approximate dynamic programming (ADP)based design tools are developed for adaptive control of aircraft control under nominal and damaged conditions. Nominal control of the system is computed with a Single Network Adaptive Critic(SNAC) derived through principles of ADP. Convergence of SNAC training is shown by reducing it to solving a set of nonlinear algebraic equations in weights. Unlike many adaptive control approaches, we develop approximate optimal control expressions to handle uncertainties. Uncertainties are calculated with an online neural network with guaranteed convergence. Longitudinal dynamics of an aircraft is used to illustrate the working of the developed algorithms. ©2009 IEEE.
