摘要

如今，隐私保护避免了信号在传输过程中的泄露。本文研究了模糊奇异系统的隐私保护问题。首先，用Takagi-Sugeno （T-S）模糊建模方法来表示非线性离散奇异系统。然后，通过输出掩码技术，迷惑窃听者获取信息。同时考虑了信号通过信道的负载问题、信号量化问题和信道衰落问题。在此基础上，给出了系统的稳定条件，并设计了满足有限时间能量峰值（E2P）性能的奇异滤波器。最后，验证了该方法的有效性。

Finite-time security E2P filter design of fuzzy discrete-time singular system

Nowadays, privacy protection avoids the disclosure of signals during transmission. This article studies the privacy protection of fuzzy singular systems. Initially, the nonlinear discrete-time singular system is represented using the Takagi-Sugeno (T-S) fuzzy modeling approach. Then, through the output mask technology, the eavesdropper is confused to obtain information. Meanwhile, the load problem of the signal passing through the channel is considered, the signal quantization is considered, and the channel fading problem is considered. On this basis, the stability conditions of the system are given, and a singular filter that satisfies the finite-time Energy-to-Peak (E2P) performance is designed. Ultimately, the proposed method’s effectiveness is substantiated.
