Summary:This paper presents a systematic model/controller order reduction
method applied to flexible aircraft. The method, based on mixed
μ-synthesis, determines which flexible modes can be truncated from
the full-order model of the aircraft and finds a corresponding reduced
order controller preserving robust closed-loop performance. This method
is of interest for practical model and controller reduction for flexible
aircraft because in this context it is important to keep the physical
interpretation of the truncated and remaining modes. Numerical examples
are given for a flexible model of a B-52 bomber and a three-mass
flexible system
