Stabilization of networked control systems with wireless sensors based on time-delay weighted fusion
时延加权融合技术的无线传感器网络控制

The problems of modeling, stabilization and design of networked control systems with wireless sensors are discussed. At first, a new model of networked control systems with wireless sensors is developed, and then a time-delay dependent weighted mean method is proposed to fuse the data from different sensors. Through model transformations and mathematical analyses, we transform this problem to the problem of stabilizing a single networked controller with multi-sensor as well as multiple random time-delays and packet loss. Using theories of jump linear system, we successfully design a static output feedback controller with mean-square stability. Finally, a numerical example is given to show that the weighted mean fusing output feedback controller has stronger robustness than the controller with conventional output feedback in the same conditions.
