Analysis and control of networked control systems based on input delay

The stabilization of networked control systems (NCSs) with time delay and packet dropout is studied. Based on the working mechanism of zero-order hold (ZOH) in actuator, the NCS is modeled as a control system with input delay. Sufficient conditions for the stability and stabilization of NCS are established by use the Lyapunov theory and time-delay systems theory. Thus, the control problem of NCSs with both time delay and packet dropout is solved effectively. Numerical example shows the effectiveness of the method.
