Abstract

A passivity-based angular rate feedback controller is proposed for a fin-controlled missile system. To augment the stability of the flight systems, rate feedback loop is designed as the inner-loop system. In the flight envelope, aerodynamics dominantly affect the flight dynamics, some of which may be taken advantage of the flight control system. In this study, passive characteristics in the flight dynamics are investigated, and the characteristics are exploited in controller design. The similarities between the classical stability augmented system and the proposed controller are analyzed. Numerical simulation is performed to demonstrate the effectiveness of the proposed controller.
