Robust control of reheat-fan engine

Abstract

In this paper, reheat-fan engine is described as class of models constructed from nominal and uncertainty model for robust control. In this class of models, uncertainty model consists of structured and unstructured uncertainty, and each model is identified from nonlinear simulation using FFT and ML technique. Then, control requirements and an augmented plant are specified. H/sub /spl infin// controller satisfying the control requirements is designed by using constant scaling matrix. Finally, efficacy of the H/sub /spl infin// controller is shown by computer simulation.
