Model Reduction of LPV Control with Bounded Parameter Variation Rates

Widowati, Widowati and Riyanto, T. Bambang (2006) Model Reduction of LPV Control with Bounded Parameter Variation Rates. The 6th Asian Control Conference .



This paper proposes a reduced-order controller of linear parameter varying systems. The parameters are available for measurement while their ranges and rates of variation are assumed to be bounded. A balancing parameter varying systems is first presented. Furthermore, a singular perturbation method of linear time invariant systems is generalized to reduce the order of the balanced systems. A reduced-order model can be obtained by setting to zero a derivative all states corresponding to smaller Qe-singular values. Based on the reduced-order model the low-order parameter varying controllers are designed by using parameter dependent H(infinite) synthesis. Effectiveness of the proposed model reduction is verified by applying it to Moore-Greitzer model of a jet engine compressor.
