摘要

摘要: 以网络控制系统为研究对象，讨论传感器发送功率对系统性能和通信能耗的影响.首先，针对无线通信系统中存在的丢包问题，根据发送功率的大小，建立系统切换模型，其中，发送功率越大，丢包率越低，系统性能越好.然后，利用平均驻留时间技术，得到系统指数均方稳定的充分条件以及发送功率的可调度条件.最后，根据以上结果，给出系统功率分配和控制器增益的协同设计算法，该算法不仅能保证系统具有理想的控制性能，同时能够使得通信能耗最优.

Abstract: This paper investigates the effects of sensor transmission power on system performance and communication energy cost of networked control system. First, by considering the packet dropout problem in wireless communication systems, a switching system control model is built based on the transmission power level, in which a larger transmission power leads to a smaller packet dropout rate, and hence a better system performance. Then by using average dwell time technique, sufficient conditions for the exponential mean square stability and schedulability requirements are obtained. Finally, a co-design framework for transmission power allocation and system stabilization is derived, which can guarantee a desired decay rate of the system with minimal communication energy consumption.
