“…To dispose of the aforementioned problem, FTC has drawn much attention because of its ability to overcome the adverse effects caused by various faults. In general, the FTC is often classified into two groups: (1) active FTC (AFTC) [8][9][10] and (2) passive FTC (PFTC). With AFTC techniques, the satisfactory performance can be ensured since the controller is reconfigured in real-time in accordance with the signals collected from the fault detection and isolation (FDI) unit.…”

The practical preset time fault‐tolerant control (FTC) problem is explored in this article for uncertain Euler–Lagrange systems with input saturation and guaranteed performance. To cope with the uncertainty of the Euler–Lagrange systems, the adaptive neural network (NN) is exploited to approximate the unknown continuous function. Most existing results that consider input saturation and actuator faults simultaneously need to design compensation strategies separately, which increases the complexity of control algorithms. To overcome the above obstacle, the Nussbaum gain technique is used to deal with the effects of input saturation and actuator faults in this article. Besides, with the help of error transformation technology and speed function, the proposed control algorithm can ensure that the tracking error converges within the preset time and its overshoot is constrained within the prescribed performance boundaries. Furthermore, the boundedness of all closed‐loop system signals is confirmed. Finally, comparative simulation results are depicted to highlight the superiority of the designed control algorithm.

Summary This article investigates an adaptive fuzzy finite‐time fault‐tolerant control (FTC) scheme for nonlinear pure‐feedback systems (PFSs) with sensor faults. The pure‐feedback system in this article includes time‐varying fault factors and unknown nonlinear functions. Choose the time‐varying fault separation method to keep the fault parameters away from the actual state to avoid coupling problems. Using the mean‐value theorem (MVT) to handle the non‐affine functions in the system and effectively decouple the control input signals. The approximation capability of the fuzzy logic systems (FLSs) is utilized to handle the unknown functions in the system and combined with the backstepping techniques for the construction of the adaptive fault‐tolerant controller. Using Lyapunov theory to verify the stability of closed‐loop system. Finally, choose two simulation examples verified the validity of the control strategy.
