Abstract:

Based on a regular and impulse-free singular controlled plant, the problem of exponential stability and modeling of dynamic output feedback networked control systems with network-induce delay and data dropout is studied. Considering network-induce delay less than or equal to one sampling period and certain data packet dropout, the dynamic output feedback networked control systems are modeled as an asynchronous dynamical-switched systems constrained by packet dropout rate. By using switched systems and linear matrix inequality approach, the sufficient conditions of exponential stability for the NCS are derived, and the exponential damping decrement and the maximum allowable dropout rate for stability are presented. A simulation example shows that the analysis method and result are valid and feasible.
