Prescribed-Time Tracking for Second-Order CPSs Against Deception Attacks via Fully Actuated System Approach

This study addresses the adaptive prescribed-time tracking control problem for second-order unknown cyber-physical nonlinear systems against deception attacks. The advantage of adopting the fully actuated system method to study second-order cyber-physical systems in this paper lies in avoiding the need to simplify the second-order systems into the first-order systems during the system control process. For the prescribed-time control strategy, an optimized prescribed time-scaling function is designed, which avoids controller singularity by introducing a constant term, ensuring that the tracking error converges to the prescribed range within a specified time. Finally, a numerical simulation is carried out to validate the proposed control method.
