具有二元传感器的线性随机系统的分布式系统辨识

Distributed System Identification for Linear Stochastic Systems with Binary Sensors

Kewei Fu, Han-Fu Chen, Wenxiao Zhao

摘要:

研究了时变网络上系数未知的线性随机系统的分布式辨识问题。为了估计未知系数,网络中的每个智能体只能访问本地系统的输入和二进制值输出。与现有的分布式优化和估计工作相比,本文考虑的二值局部输出观测问题具有挑战性。通过假设网络中的智能体可以与其相邻的邻居进行通信,提出了一种基于随机逼近的分布式辨识算法,并建立了估计的一致性和收敛性。最后给出了一个数值算例,仿真结果与理论分析相一致。

英文摘要:

The problem of distributed identification of linear stochastic system with unknown coefficients over time-varying networks is considered. For estimating the unknown coefficients, each agent in the network can only access the input and the binary-valued output of the local system. Compared with the existing works on distributed optimization and estimation, the binary-valued local output observation considered in the paper makes the problem challenging. By assuming that the agent in the network can communicate with its adjacent neighbours, a stochastic approximation based distributed identification algorithm is proposed, and the consensus and convergence of the estimates are established. Finally, a numerical example is given showing that the simulation results are consistent with the theoretical analysis.
