EVENT-TRIGGERED H∞ STATIC OUTPUT FEEDBACK CONTROL OF DISCRETE TIME PIECEWISE-AFFINE SYSTEMS

This paper is concerned with the problem of H-infinity event-triggered output feedback control of discrete time piecewise-affine systems. Relying on system outputs, a piecewise-affine triggering condition is constructed to release communication burden. Resorting to piecewise Lyapunov functional and robust control techniques, sufficient conditions are built to ensure the closed-loop systems to be asymptotically stable with the prescribed H-infinity performance. By utilizing a separation strategy, the static output feedback controller is solved by means of linear matrix inequalities. The validity of the proposed method are demonstrated by numerical examples.
