Abstract:Exponential stability and controller design problem for dynamical output feedback networked control systems(NCSs) with network-induce delay and data packet dropout is studied.Based on a fixed data packet dropout rate and constant time-delay not more than one sampling period,the dynamical output feedback NCS is modeled as an asynchronous dynamical system constrained by configuration event rates.By using linear matrix inequality method,sufficient and necessary conditions for exponential stability of the system constrained by network switching on rates are derived,and the controller design method is presented.Simulation example shows that the results are valid and feasible.
Keywords:Networked control systems  Exponential stability  Controller design  Linear matrix inequality  Timedelay  Data packet dropout
