LFT-based uncertainty modelling and /spl mu/-analysis of the HIRM+ RIDE flight control law

This paper considers the problem of generating LFT-based uncertainty models for the robustness analysis of the HIRM+ aircraft using the structured singular value /spl mu/. Robustness properties of the RIDE controller are evaluated according to criteria currently in use by the European aircraft industry for the clearance of flight control laws. The proposed analysis approach is shown to be both rigorous and efficient, and demonstrates increased potential for automation of the flight clearance task.
