Full Differential Privacy Preserving for Switched LPV Systems

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 H-infinity control design with dual asynchronization analysis are given. Finally, simulation results verify the effectiveness of the proposed method.
