This paper addresses the stability control problem for networked control systems (NCSs) subject to hybrid disturbances including Denial-of-Service (DoS) attacks, fading channels, and state quantization. In this configuration, the control commands of the controller, are sent to the plant via fading channels. A dynamic quantizer located between the sensor and the controller is employed to discretize the system state. To characterize the random duration and frequency of DoS attacks, a Markov process is utilized to model the resulting packet loss. By employing the Lyapunov stability theory, we derive sufficient conditions in the form of linear matrix inequalities (LMIs), ensuring the stochastic stability of NCSs. Numerical simulations validate the efficacy of the proposed control strategy.

摘要

This paper addresses the stability control problem for networked control systems (NCSs) subject to hybrid disturbances including Denial-of-Service (DoS) attacks, fading channels, and state quantization. In this configuration, the control commands of the controller, are sent to the plant via fading channels. A dynamic quantizer located between the sensor and the controller is employed to discretize the system state. To characterize the random duration and frequency of DoS attacks, a Markov process is utilized to model the resulting packet loss. By employing the Lyapunov stability theory, we derive sufficient conditions in the form of linear matrix inequalities (LMIs), ensuring the stochastic stability of NCSs. Numerical simulations validate the efficacy of the proposed control strategy.
