Abstract: In the condition of sensor adopted time driven and controller and actuator adopted event driven assuming that the transfer delay is shorter than the sampling period and the lose rate of date packet transfer is given, the singular networked control system was modeled as an asynchronous dynamical system for a class of the regular, impulsive-free and impulsive observable singular networked control systems with delay and date packet dropout. At the same time, state observer keeps structural of the systems, so based on the state feedback controller of the original system, the stability conditions of the system were proved with the Lyapunov function and LMI method. At last, a simulation example revealed the effectiveness of the proposed method.
