Full Differential Privacy Preserving for Switched LPV Systems
研究了切换LPV系统中调度变量、切换信号和系统输出三类信号的完全差分隐私保护问题，提出了三种差分隐私定义及拉普拉斯/均匀噪声设计方法，并给出了H∞控制设计的充分条件。
In this article, the full differential privacy-preserving problem for switched LPV systems is concerned. The security of a control system is the ability to avoid intentional sabotage or accidental interference affecting its normal operation. For switched LPV systems, it contains both internal (scheduling variable and switching signal) and external (system output) information that needs to be protected, we adopt differential privacy to achieve its full privacy preserving. The resulting challenges are: 1) privacy design for three types of system signals and 2) dual asynchronization analysis under triple privacy noise. Accordingly, three differential privacy definitions and Laplace (resp. uniform) noise design methods are presented. Sufficient conditions for <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$H_{\infty}$</tex-math> </inline-formula> control design with dual asynchronization analysis are given. Finally, simulation results verify the effectiveness of the proposed method.
