Region of attraction Analysis for Adaptive Control of Wing Rock System

This paper introduces a numerical method for region of attraction (ROA) estimation the adaptive control system in polynomial form. A classical controller with sigma modification on suppressing wing rock motion is revisited. Using nonlinear analysis technique based sum squares optimization, ROA origin computed respect to potential measurement error. The obtained result gives solid guarantee allowable initial conditions where still able suppress motion. It provides confidence operating under some unforeseen practice.
