Observer-based controller design for networked systems with multiple packet losses and mixed delay

The paper focuses on a stabilizing controller design problem for networked systems with quantization, mixed delays, and a series of packet losses due to the signal transmission through the unreliable communication channel. Quantization of both sensor-to-controller and controller-to-actuator are taken into account for the networked systems, and the distributed time delay is also considered in the network channel. Sufficient conditions for designing the controller as well as the system parameters can be obtained by solving certain linear matrix inequalities. Finally, the effectiveness of the designed method is proved by a numerical example.
