Application of Reduced-order LPV Controller to Jet Engine Compressor Model

Abstract

This paper purposes a reduced-order controller of linier parameter variying sistems.The parameter are available for measurement while their ranges and rates are assumed to be bounded. A balancing parameter variying systems is first presented. futhermore, a singular perturbation of linear time invariant systems is generalized to reduced the order of the balanced systems. Bsed on the reduced-order model the low-order parameter variying controllers are designed by using parameter dependent H1 synthesis. Effectiveness of the proposed model reduction method is verified buy appliying it to the jet engine compressor model. Finnaly, the closed loop performence of the full-order LPV controllers is compared with that of reduced-order LPV controllers.
