A design method of state estimation observer under outliers and data-lost environment is proposed in this paper. In networked control systems, the data-lost is one of the most important topic for solving. When data-lost occurred, the output data for the control system is disappeared. The data-lost is significant problems if we want to use state feedback. To overcome negative impact by outliers and data-lost, we propose a method to disappear negative impact by outliers and data-lost using median information. The effectiveness of the proposed observer is evaluated by numerical examples.
