摘要: 在网络化环境下对线性系统辨识中的多敏感器分配策略进行研究. 为节约通信带宽,引入了二值量化机制;为解决数据传输时面临的冗余和通道拥堵问题,提出一种差分驱动的事件通信机制,并证明这种机制具有完全信息复原能力,同时给出其通信率. 基于接收端的可用数据,构造各个有限脉冲响应系统的辨识算法,分析其收敛性能. 进而,将通信资源受限下的多敏感器分配问题建模成带约束的优化问题,设计一种改进的遗传算法,给出最优方案. 用数值例子验证理论结果的正确性和有效性.

Abstract: This paper investigates the multi-sensor allocation strategy problem for linear system identification in a networked environment. A binary quantization mechanism is introduced to save communication bandwidth. For addressing the redundancy and channel congestion issues during data transmission, a differential event driven communication mechanism is proposed, and its communication rate is provided. It is shown that such mechanism has the capability of complete information recovery. Based on the available data at the receiving end, identification algorithms for various finite impulse response systems are constructed, and their convergence performance is analyzed. Furthermore, the multi-sensor allocation problem under constrained communication resources is modeled as a constrained optimization problem, and an improved genetic algorithm is designed to give the optimal solution. Finally, a numerical example is used to verify the correctness and effectiveness of theoretical results.

Key words: multi-sensor, system identification, event driven mechanism, constrained communication resources
