Dynamic Inversion with Adaptive Augmentation for a High-Speed Guided Projectile

Abstract

Dynamic inversion control schemes offer a systematic approach to flight control design when the relevant plant dynamics are well characterized. This work presents a dynamic inversion scheme for the autopilot of a high-speed projectile. The relevant aerodynamic coefficients for the projectiles short period dynamics are well characterized and used here to develop a scheduled linear dynamic inversion controller. An adaptive modification is included to correct the aerodynamic coefficients in the outer loop of the control architecture where the greatest sensitivity to parametric uncertainty is found. The resultant approach is exercised through a series of nonlinear simulations and shows graceful degradation in the presence of a variety of uncertainties.
