Abstract

Flight control law for Reusable Launch Vehicles (RLV) is usually a job of multivariable control design, traditional robust analysis for single input and single output system is not fit for RLV. So a method based on μ-analysis is presented for evaluating the stability margin of a multivariable flight control system and the robustness of model uncertain aerodynamics. μ-analysis has less conservative by using a structured singular value, and is more suitable for engineering applications.
