DISCRETE-TIME LPV CONTROLLER FOR ROBUST MISSILE AUTOPILOT DESIGN

摘要

This paper proposes a method to obtain a discrete-time LPV (Linear Parameter Varying) controller for a non-linear system represented with the LFT (Linear Fractional Transformation) framework. This synthesis can be integrated into a loop-shaping/LPV approach to obtain a discrete gain-scheduled control law. A detailed application of this method is here performed with a classical example of non-linear missile pitch-axis control.
