Applying μ-synthesis to missile autopilot design

μ-synthesis combines the structured singular value and H _∞ control to design compensators for plants with structured uncertainty. The application of μ-synthesis to the design of a flight control system for a highly maneuverable tail controlled missile is discussed. Performance goals are given in the time and frequency domains and include time constant, overshoot, stability margins, and high-frequency attenuation. The resulting control law desensitizes the system´s performance to structured variations in the missile´s aerodynamic properties and provides some robustness, in both a single-loop and a multiloop sense, to variations and/or perturbations not included in the uncertainty model
