Switching Hinf Control Synthesis Designs for Networked Control Systems

This paper investigates joint stabilization and disturbance attenuation problem of for a class of networked control systems subject to disturbance and packet dropout in the transmission channel. A condition for exponential stabilization of networked control systems under a given switching rule is derived by employing multiple Lyapunov-like functions. A design solution for switching H-inf control that compensates for packet dropout and attenuates disturbance is found in terms of linear matrix inequalities. Impulse impact is also studied in order to reduce theory-application discrepancy switching. An illustrative example is given along with its simulation results to demonstrate both feasibility and efficiency of the proposed method.
