本文通过基于状态估计器的自适应滑模控制（SMC）策略，研究了随机马尔可夫跳变网络物理系统（SMJCPS）针对执行器故障（AF）、随机注入攻击（ROIA）和不可访问状态的安全控制问题。状态的知识是由一个不需要任何输入信息的估计器生成的，从这些信息中建立了一个新的线性类型的切换曲面（SSL）。然后，开发了一个自适应SMC输入，以确保在随机噪声、未知ROIA和潜在AF的情况下，在有限的步长内实现SSL。鉴于SSL和随机稳定性理论的到来，在AF、ROIA和更普遍的不确定过渡率的情况下，推导了目标SMJCPS在定义SSL上运行的一个新的随机稳定准则。最后，进行了仿真研究，实现了提出的控制方案，并通过隧道二极管电路模型进行了验证。
This article investigates the issue of security control for stochastic Markov jump cyber-physical systems (SMJCPS) against actuator failures (AF), randomly occurring injection attacks (ROIA), and inaccessible states by virtue of state estimator-based adaptive sliding mode control (SMC) strategy. The knowledge of the states is generated with an estimator not requesting any input information from which a novel switching surface of linear type (SSL) is established. Then, an adaptive SMC input is developed to ensure the attainability of the SSL in limited steps, almost surely under stochastic noise, unknown ROIA, and potential AF. In the light of the arrival of the SSL and stochastic stability theory, a new stochastically stable criterion for the target SMJCPS operating on the defined SSL is deducted in the occurrence of AF, ROIA, and more generally uncertain transition rates. At last, a simulation study is performed, in which the raised control scheme is realized and certified by a tunnel diode circuit model.
