A State Space Approach to Body Bending Compensation for Missile Autopilot Design

A state space approach to the design of a body bending compensator is presented. A simple model composed of a flexible mode and a rigid body mode (represented by a constant) is used as a model for an observer based body bending compensator. A robustness recovery technique is utilized to generate a compensator that is less sensitive to uncertainty in the body bending frequency. A comparison between this design approach and a standard notch filter is presented.
