Observer-based nonlinear control allocation

Abstract

In this paper, a Lyapunov-based approach is proposed for control allocation problem based on output feedback and model reference control. A nonlinear observer design approach for a general class of nonlinear systems is used to estimate the unmeasurable system states. The proposed approach ensures that the estimated states exponentially converge to their true values and the designed closed-loop system converges to a given stable reference model as t → ∞. © 2010 AACC.
