Affine LPV modelling and its use in gain-scheduled helicopter control

A key step in the quadratic H/sup /spl infin// performance method for gain-scheduled control of MIMO systems is the modelling of the plant dynamics. This paper describes a practical technique for modelling affine linear parameter varying (LPV) systems which is then used in the design of a gain-scheduled controller for a Lynx helicopter. The method is demonstrated in simulation and shown to be an effective modelling strategy for gain-scheduled control.
