“…36,37 The SMC essential properties are the suitable response, the robustness versus parametric uncertainties, and computational simplicity in comparison with other robust control approaches. [38][39][40] The design procedure of conventional SMC has been segregated to two phases as: reaching phase and switching phase. In the reaching phase, the control law is specified to oblige the system state variables to follow the determined sliding surface.…”

SummaryIn this study, a novel strategy of the adaptive non‐singular second‐order terminal sliding mode (SOTSM) control technique for the finite time stabilization of cyber‐physical systems (CPSs) is proposed. By utilizing the proposed nonlinear sliding surface, the reaching phase is obliterated and the entire system's robust operation is ameliorated. The offered online adaptive laws deal with the unwanted disturbances and cyber‐attacks, so that there is no need to identify their upper bounds. The designed adaptive non‐singular SOTSM control technique provides the strong robustness of CPSs in the presence of the unwanted disturbances and cyber‐attacks. Also, it guarantees high precision, pliable performance, fast response, smooth control, chattering‐free operation without transient oscillations, and appropriate convergence in the finite time. Numerical simulation results demonstrate effectiveness and success of the proposed adaptive non‐singular SOTSM control technique compared to the results of state feedback control (SFC), conventional sliding mode control (SMC), and integral‐type SMC methods.

“…Because of lengthy information communication, the inherent time delay within the communication channel is negligible [42,43]. Master-slave synchronization [44] and stability analysis of the teleoperation systems under various time delays such as constant delay [11], time-variable delays [45,46] and random delays [47] are considered as interesting topics in the field of teleoperation systems.…”

In this study, a novel method based on a robust adaptive fuzzy control approach is developed for nonlinear teleoperation systems. Its main objectives are to ensure system stability and properly mitigating parametric uncertainties stemming from external disturbances and un‐modelled dynamics. For the communication channel, instead of the direct transmission of environmental torque signals, the approximated environmental parameters by the fuzzy system are transmitted to the master side for the prediction of environmental torque, thus successfully avoiding the transmission of the power signals in the delayed communication channel and solving the passivity problem in the teleoperation system. Besides, a trajectory generator is employed in the master side, whereas a trajectory smoothing is provided in the slave side. Theoretically, it was proven that both position tracking and force feedback problems are attained. Using Lyapunov stability analysis, this work illustrates that the robust adaptive fuzzy controller based on the backstepping approach guarantees the system's asymptotic stability. Simulation results confirm the efficiency of the suggested control technique in achieving the stability and tracking objectives of the uncertain nonlinear teleoperation system.

“…In addition, some effective and robust control strategies that are not targeted at CAVs also need to be further studied and are worthy of being applied to deal with CAV cyberattacks [ 15 , 16 ], but we will not make a further detailed summary here.…”

Connected and automated vehicles (CAVs) present significant potential for improving road safety and mitigating traffic congestion for the future mobility system. However, cooperative driving vehicles are more vulnerable to cyberattacks when communicating with each other, which will introduce a new threat to the transportation system. In order to guarantee safety aspects, it is also necessary to ensure a high level of information quality for CAV. To the best of our knowledge, this is the first investigation on the impacts of cyberattacks on CAV in mixed traffic (large vehicles, medium vehicles, and small vehicles) from the perspective of vehicle dynamics. The paper aims to explore the influence of cyberattacks on the evolution of CAV mixed traffic flow and propose a resilient and robust control strategy (RRCS) to alleviate the threat of cyberattacks. First, we propose a CAV mixed traffic car-following model considering cyberattacks based on the Intelligent Driver Model (IDM). Furthermore, a RRCS for cyberattacks is developed by setting the acceleration control switch and its impacts on the mixed traffic flow are explored in different cyberattack types. Finally, sensitivity analyses are conducted in different platoon compositions, vehicle distributions, and cyberattack intensities. The results show that the proposed RRCS of cyberattacks is robust and can resist the negative threats of cyberattacks on the CAV platoon, thereby providing a theoretical basis for restoring the stability and improving the safety of the CAV.
