In this paper,we present an output regulation method for unknown cyber-physical systems(CPSs)under time-delay attacks in both the sensor-to-controller(S-C)channel and the controller-to-actuator(C-A)channel.The proposed approach is designed using control inputs and tracking errors which are accessible data.Reinforcement learning is leveraged to update the control gains in real time using policy or value iterations.A thorough stability analysis is conducted and it is found that the proposed controller can sustain the convergence and asymptotic stability even when two channels are attacked.Finally,comparison results with a simulated CPS verify the effectiveness of the proposed output regulation method.

Secure H_(∞) control against time-delay attacks in cyber-physical systems

Journal of Control and Decision 2022年第4期9卷 420-430页

This paper is concerned with the secure H_(∞) control problem for cyber-physical systems(CPSs)under time-delay attacks,which cause the systems’information to be received with delays.Through transforming the H_(∞) control problem to a two-player zero-sum game problem,the H_(∞) controller can be obtained by solving the saddle point for the game.Due to the unknown system parameters,a model-free reinforcement learning(RL)method is applied,and the measurement feedback controller is designed based on the historical inputs and the tracking errors.To obviate the requirement of the initial admissible policy,the value iteration(VI)of the adaptive dynamic program(ADP)algorithm is proposed to solve the approximate saddle point.Moreover,the con-vergence of the proposed algorithm is proved.Finally,a networked circuit system is employed to show the effectiveness of the proposed methods.
