TL;DR
A time-delay dependent weighted mean method is proposed to fuse the data from different sensors and successfully design a static output feedback controller with mean-square stability.
Abstract
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.
