Sliding Mode Control for Persistent Dwell‐Time Switched System Under Multi‐Node Round‐Robin Protocol and Replay Attacks

ABSTRACT This work investigates the output‐feedback‐based sliding mode control (SMC) issue for a class of persistent dwell‐time (PDT) switched systems suffering from replay attacks and multi‐node round robin protocol (MN‐RRP). A distinctive aspect of MN‐RRP is that more than one node can be selected to transmit signals at the same instant, and the count of such selected nodes fluctuates as the system switches. Firstly, in the presence of replay attacks and MN‐RRP scheduling, an adaptive dynamic output‐feedback (ADOF) sliding mode controller is designed based on the actual measured output information. In addition, the reachability of the specified sliding surface and the input‐to‐state stability in probability (ISSiP) of the resulting PDT switched system are discussed, and sufficient conditions are obtained correspondingly. Lastly, a simulation case is presented to illustrate the proposed SMC scheme.
