Finite-time H-infinity control of networked control systems with normbounded disturbance

This paper is concerned with the finite-time H∞ control problem for networked control systems (NCSs) with time-varying exogenous disturbances. The finite-time state feedback controller is proposed to guarantee the closed-loop system is finite-time bounded (FTB) and reduces the effect of the disturbance input on the controlled output to a prescribed level. A sufficient condition is presented for the solvability of this problem, which can be reduced to a feasibility problem involving linear matrix inequalities (LMIs). Finally, an example is given to show the validity of the methodology.
