Reduced order $H_\infty$ loop-shaping control of a missile pitch axis over a wide flight envelope

Abstract

This papers deals with the gain-scheduled control of the pitch channel of a missile with large variations of Mach and altitude. A reduced order $H_\infty$ loopshaping control technique allows designing discrete-time controllers of very small order for different flight points; the final control law consists in interpolating the parameters of the controllers so obtained.
