Description
Summary:This work addresses privacy-preserving sliding mode control issue of interval type-2 fuzzy systems under resource-constrained environments. A novel dynamic mask-based encoding-decoding scheme is developed to simultaneously ensure data confidentiality and improve communication efficiency. Firstly, a time-varying mask function is employed to transform original system states into secured variables for protecting the privacy of sensitive state information. Subsequently, the masked states are encoded via a dynamic quantizer before being transmitted over the digital channels with finite coding length, and the coding scheme is given for masked state and quantizer's parameter. Meanwhile, a fuzzy sliding mode controller is designed utilizing only decoded masked states, under which sufficient conditions are obtained to ensure the ultimate boundedness of closed-loop systems and the reachability of the specified sliding surface. Finally, numerical example is used to demonstrate the effectiveness of the proposed privacy-preserving sliding mode control scheme.
