Linearization of a Six-Degree-of-Freedom Missile for Autopilot Analysis

Abstract

model reduction methods, it is possible to reduce the controller order to a lower level with acceptabledegradation in control performance. However, using controller approximationwith fewer states implies an increase in 1. Still, there are open numerical problems in connectionwith actual implementation in 1-synthesis. 2) The robust performance (RP) condition in Eq. (8) is identical to a robust stability (RS) condition with an additional perturbation block 1P . In other words, the RP condition is more severe than the RS condition, and so there is no doubt of RS in this illustrative satellite case, where the RP condition is satisŽ ed.
