Output feedback control networked control systems based on singular controlled plant

Based on a regular, impulse-free and linear time-invariant singular controlled plant, the problem of output feedback control for a class of networked control systems with uncertain time-delay is studied. For uncertain time-delay less than or equal to one sampling period, choosing a dynamical output feedback controller, the networked control system is modeled as a linear time-variant normal system with uncertainty. By using Lyapunov theory and linear matrix inequality approach, the condition to keep the system stable is presented. A numerical example is given to show the effectiveness of the proposed method.
