Output Feedback Stabilization of Networked Systems Subject to Actuator Saturation and Packet Dropout

The problem of output feedback stabilization is studied for networked systems subject to actuator saturation and random packet dropout. It is assumed that the packet dropout in output channels obeys the Bernoulli random binary distribution. An observer-based output feedback control method is proposed to achieve the local and exponential mean-square stability of the closed-loop system, where the latest packet kept in the buffer is used as the input of the observer when the packet containing the measurement of the plant is lost. A numerical example is provided to demonstrate the effectiveness of the proposed method.
