Anti-windup design for aircraft flight control

This paper addresses the problem of static anti-windup strategy for linear unstable control systems with saturated dynamics describing some aircraft flight control. The approach is based on the use of quadratic Lyapunov functions, S-procedure and a sector nonlinearity description for modelling the behavior of the closed-loop nonlinear system. Anti-windup design is investigated to increase both a domain of admissible references to track and a safety region over which the stability of the resulting closed-loop saturated system is ensured.
