Dynamic memory event‐triggered fault‐tolerant control of Markov jump systems based on proportional‐integral intermediate observer under deception attacks

Abstract This paper proposes a proportional‐integral intermediate observer‐based fault‐tolerant control method for Markov jump systems under a dynamic memory event‐triggered scheme. In order to save network communication resources, a new dynamic memory‐based event‐triggered condition is designed by incorporating dynamically adjusted memory buffers. A mode‐dependent intermediate observer is built by introducing an output error integral term to achieve better tracking performance. The corresponding memory‐based event‐triggered fault‐tolerant controller is explored for the first time to overcome the effect of deception attacks and unknown faults. The sufficient conditions for the design of the proportional‐integral observer and the controller are derived. Ultimately, two cases are given to demonstrate the efficacy of the proposed approach.
