Missile autopilot design using a gain scheduling technique

A recently developed framework for gain scheduled control system synthesis is applied to a missile autopilot design problem. In contrast to previous approaches, low order linear autopilots designed at discrete operating points using classical control techniques are gain scheduled. Also, mach number, modeled as a measured, time-varying exogenous signal, is viewed as a disturbance to be rejected in the linear design phase, leading to improved steady-state tracking performance
