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

摘要

This paper describes the synthesis of a self scheduled controller robust with respect to parametric uncertainties. Traditionally, scheduling is done a posteriori by interpolation of gains computed for several points within the parameter space. The method proposed here, named (Mu-μ)-iteration, is based on worst-case analysis and multi-model eigenstructure assignment. It permits the designer to synthesize a robust low order controller by considering a priori its dependence of some scheduling parameters. The method is then applied to derive a robust missile autopilot
