| 中文摘要 |
| 本文研究了无线传感器网络控制系统的建模、稳定性与控制器设计问题. 首先建立一个新的无线传感器网络控制系统模型, 然后提出一种用于多个传感器数据融合的时延相关加权均值方法, 并通过系统建模及分析, 把无线传感器网络控制系统稳定性问题转换成为具有多个传输时延和丢包现象的多传感器单控制器网络控制系统稳定性问题, 并利用线性跳变系统理论成功地设计出使系统均方稳定的静态输出反馈控制器. 最后通过仿真实例说明,在同等条件加权均值融合输出控制器比一般输出控制器具有更强的鲁棒性. |
| 英文摘要 |
| 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. |
