Abstract : "This paper considers the quantized dynamic output feedback control of networked control system(NCS)
with random packet dropout in both sensor-to-controller and controller-to-actuator channels. The packet losses in
the two links are modeled as two independent Markov chains and the NCS is modeled as a Markov jump system.
The stochastic switching signal for the quantized output feedback controller is designed to be a function of the
number of successive packet loss in both of the two channels. Quantization density varies with the networked
load condition. Then a sufficient condition of the stochastic stability with a prescribed H∞ performance level
is established based on the Lyapunov-Krasovskii function approach. Furthermore, a quantized output feedback
controller is obtained via the cone complement linearization method. Finally, simulation results are provided to
verify the effectiveness of the proposed method."
