Network-based H∞ control of systems with packet dropout and time-varying sampling period

This paper is concerned with the problem of H-infinity controller design for networked control systems (NCSs) with time delay, packet dropout and time-varying sampling period. The considered NCSs may receive more than one control input during a sampling period. A multi-objective optimization methodology in terms of linear matrix inequalities (LMIs) and the discrete Jensen inequality are adopted to deal with the problem of H-infinity controller design for NCSs with time-varying sampling period. The proposed H-infinity controller design is also applicable for NCSs with constant sampling period. The simulation results illustrate the effectiveness of the proposed H-infinity controller design.
