Adaptive Double Integral‐Type Second‐Order Terminal Sliding Mode Controller Design for Disturbed Uncertain <scp>CPSs</scp> Against Cyber Attacks on Sensors and Actuators

ABSTRACT This article presents a novel Adaptive Double Integral‐Type Second‐Order Terminal Sliding Mode (ADITSOTSM) control policy for favorable and swift stabilization of the disturbed uncertain Cyber‐Physical Systems (CPSs) in finite time. The offered double integral‐type switching surface elides the approaching step and meliorates the system's robustness. Real‐time adaptive laws are expanded for coping with unwanted disturbances, parametric uncertainties, and cyber attacks on sensors and actuators, so that their upper bounds designation is not indispensable. The recommended strategy guarantees the disturbed uncertain CPSs robust functionality against rigorous cyber attacks on sensors and actuators. In addition, it provides swift response, smooth and robust control, high carefulness and more flexible operation, finite time convergence, without chattering, and no transient fluctuations. Comparing the simulation results with conventional, adaptive integral‐type sliding mode, and state‐feedback control depicts the introduced technique's high success and effectiveness.
