Design of adaptive parameter observer and laser network controller based on sliding mode control technology

In this work, we extend the sliding mode control technology so that it can be applied to laser network synchronization. Firstly, the adaptive parameter observer is designed and the uncertain parameters in the synchronization target are effectively identified based on the extended sliding mode control technology. Furthermore, we design the laser network controller in order to achieve complete synchronization between the laser network and the synchronization target. In our strategy, the designed network controller is very simple. The complex Lyapunov function is not required, and the only work required is to determine the range of adjusting parameters for achieving synchronization. Therefore, this technology is simple and practical.
