Gain-Scheduled Autopilot Design with Anti-Windup Compensator for a Dual-Spin Canard-Guided Projectile

Abstract

This paper explores the design of an autopilot for a dual-spin guided projectile taking into account input saturations. The projectile full nonlinear model is described and then put in a quasi-LPV form suitable for controller synthesis. A baseline gain-scheduled autopilot is then computed without taking into account the saturation nonlinearities. As a major contribution of this paper, the impact of saturations is next highlighted through a degraded flight scenario, and an anti-windup compensator is added to the closed-loop to counteract their effects. The improvements brought by the anti-windup are then evaluated through Monte Carlo simulations.
