A robust self-scheduled missile autopilot: design by multi-model eigenstructure assignment

This paper describes the synthesis of a self-scheduled controller robust wi th respect to parametric uncertainties. Traditionally, scheduling is done a posteriori by interpolation of gains computed for several points within th e parameter space. The method proposed here. named (Mu-mu)-iteration, is ba sed on worst-case analysis and multi-model eigenstructure assignment. It pe rmits the designer to synthesize a robust low order controller by consideri ng a priori its dependence of some scheduling parameters. The method is the n applied to derive a robust missile autopilot. (C) 2001 Elsevier Science L td. All rights reserved.
