Abstract

A nonlinear missile model with time-varying uncertain parameters is controlled with a simple feedback linearisation and time-scale separation design, with synthesis based on the nominal model and full state feedback. The closed-loop system is then represented as a linear fractional transformation (LFT). A robust H_∞ filter is designed for the controlled plant, to estimate unknown states. Robust stability of the closed-loop system is then verified by using a scaled linear differential inclusion (LDI) technique.
