网络攻击下马尔可夫跳变系统的量化输出反馈安全控制
Secure quantized output-feedback control of Markovian jump systems under cyberattacks
摘要
Abstract
This paper investigates the issue of designing secure quantized output-feedback control for Markovian jump systems under cyberattacks.A probabilistic model comprising two Bernoulli random variables is first introduced to capture the stochastic characteristics of network attacks.A switching quantization strategy is then developed by combining logarithmic and uniform quantizers,achieving an effective trade-off between quantization accuracy and control performance.Finally,an output-feedback secure controller is designed to mitigate the adverse effects induced by network attacks.Utilizing Lyapunov stability theory and Finsler's lemma,sufficient conditions are derived to ensure the stochastic boundedness and stability of the closed-loop system.The effectiveness and practicality of the proposed control strategy are demonstrated through numerical simulations.关键词
