N2 - In this paper, aircraft with control surface impairment faults is modelled as a set of affine parameterdependent nonlinear systems with polynomial vector fields. Based on the Lyapunov stability theorem, sufficient conditions to test the stability of the closed-loop system are presented. The synthesis problem of stabilizing feedback controllers to enlarge the region of attraction is converted to an optimization problem based on sum-of-squares polynomial. Design and simulation results for the longitudinal model of an F-8 aircraft are presented to illustrate the effectiveness of proposed approach.
