Title M-MRAC for Nonlinear Systems with Bounded Disturbances.
Publication Date Dec 2011
Media Count 6p
Personal Author K. Krishnakumar V. Stepanyan
Abstract This paper presents design and performance analysis of a modified reference model MRAC (M-MRAC) architecture for a class of multi-input multi-output uncertain nonlinear systems in the presence of bounded disturbances. M-MRAC incorporates an error feedback in the reference model definition, which allows for fast adaptation without generating high frequency oscillations in the control signal, which closely follows the certainty equivalent control signal. The benefits of the method are demonstrated via a simulation example of an aircraft's wing rock motion.
