摘要 为了提高一致性滤波精度,克服传感器网络的通信带宽和能量限制,基于二阶分布式一致性算法,提出了离散的一致性滤波算法,并基于量化通信,在改进概率量化的基础上,提出了量化一致性滤波算法。 分析了量化、非量化一致性滤波算法的收敛性,证明了一致性滤波算法的收敛性。仿真结果表明,离散一致性滤波精度高于一阶一致性滤波精度,量化一致性滤波也具有较好的滤波精度。

英文摘要 In order to improve the accuracy of consensus filters, and overcome the bandwidth and power constraint in sensor networks, the paper proposed a discrete-time consensus filter aglorithm, meanwhile, based on modified probabilistic quantization, the paper proposed a quantized consensus filter with quantization communication.The paper analyzed the convergent performance of the consensus filter with quantization and non-quantization, and proved that the consensus filter was convergent.By simulations, the results show that the filtering accuracy of the consensus filter is higher than that of the first-order consensus filter, and the quantized consensus filter performs well.
