Dynamic Output Feedback Control of Nonlinear Cyber-Physical Systems under DoS Attacks: A T-S Fuzzy Resilient Control Approach

In this paper, the dynamic output feedback control problem of nonlinear cyber-physical systems (CPSs) under denial-of-service (DoS) attacks is addressed. The main contributions are given as follows: (1) A novel T-S fuzzy resilient control approach is developed to resist the DoS attacks of nonlinear CPSs. (2) Compared with the existing cyber attacks of CPSs, a general nonlinear CPSs consisting of the interconnected subsystems is considered. Specifically, a new dynamic output feedback controller is developed by employing a switching mechanism. With the application of this controller, the closed-loop CPSs can be modelled as T-S fuzzy switching systems. Moreover, the exponential convergence of CPSs can be guaranteed by using the Lyapunov theory and the dwell time method. Finally, an illustrative example is used to demonstrate the effectiveness and efficiency of the proposed method.
