Abstract:
This article investigates a sliding-mode resilient control problem for uncertain strict-feedback nonlinear cyber-physical systems (CPSs) subject to deception attacks. The main characteristic of the proposed sliding-mode control method is its ability to mitigate undesirable system behaviors caused by deception attacks in a fixed-time interval. In particular, a novel fixed-time integral nonsingular terminal sliding-mode (INTSM) surface is designed recursively by adding a power integrator (API) technique, wherein the fractional power can be chosen to ensure the fixed-time stability of the closed-loop system and to estimate the upper bound of settling time. In addition, an adaptive super-twisting reaching law is proposed to counteract the deception attacks and ensure the continuous control action of CPSs, effectively reducing the effects of the chattering problem. Simulation results are given to demonstrate the effectiveness of the proposed sliding-mode resilient control scheme.
