Stability of Networked Control Systems with Time Delays and Data-Packet Losses

Stability of the networked control systems with network-induced delays and packet losses is investigated by considering a packet loss as a special kind of delay. A dynamic feedback controller was introduced to stabilize the networked control systems and improve their dynamic performance. The expression of total network-induced delay including the sensor-to-controller delay and the controller-to-actuator delay is presented, the networked control system model established, and the stability theorem proved. The simulation results also illustrated the effectiveness of the proposed approach.
