An LFR approach to varying sampling control of LPV systems: Application to AUVs

This paper deals with the varying sampling control of Linear Parameter Varying (LPV) systems, where varying sampling can be used to accommodate limited computation or sensory resources. A discrete-time Linear Fractional Representation of a LPV system is used to design a gain-scheduled controller, where both varying or uncertain parameters of the plant and the sampling rate are gathered in a unique varying parameters structure. The method is successfully applied for the case of the altitude control of an Autonomous Underwater Vehicle (AUV).
