Linear time invariant versus linear parameter varying reduced order controller design for Aircraft Model

Abstract

The applicability of parameter varying reduced order controllers to aircraft model is presented. The generalization of the balanced singular perturbation method of linear time invariant (LTI) system is used to reduce linear parameter varying (LPV) system. Based on the reduced order model the low-order LPV controller is designed by using H(infinity)synthesis technique. The performance of the reduced order controller is examined by applying it to lateral-directional control of aircraft model. Furthermore, the time responses of the closed loop system with reduced order LPV controllers and reduced order LTI controller is compared.
