STABILITY ANALYSIS OF CLOSE-LOOP FLIGHT CONTROL SYSTEM AND ESTIMATION OF REGION OF ATTRACTION

Usually to design an autopilot for a missile, varying-parameter linear models is used. In this approach, Gain Scheduling methods are utilized and different approaches are used for interpolation. But the stability analysis of close-loop for these systems is an essential challenge. In this paper, a new approach to analyse the stability of these nonlinear systems has been developed. Also using convex optimization methods, the region of attraction of the system has been estimated which determine the variation of region of attraction and in different points and specify the stability of close-loop system around the origin.
