“…Theorem 1. Consider the system (12) under sensor faults (13), Assumption 1, the adaptive practical fixed-time tracking controller designed using the practical control law u, virtual control laws 𝛼 i given by ( 17)-( 19) and adaptive law (20). The origin of the system is practically fixed-time stable even though the sensor faults take place.…”

“…Until now, FTC methods for sensor faults have been reported. The authors of Reference 20 investigate the problem of FTC for nonlinear systems with sensor/actuator fault. In Reference 21, an active FTC method is studied for unmanned underwater vehicle with sensor faults, and the acceptable tracking performance of the faulty system can be achieved with the proposed approach.…”

This article focuses on the problem of adaptive fixed-time dynamic surface fault-tolerant control for a class of strict-feedback nonlinear systems subject to sensor faults. The sensor faults include bias, drift, loss of accuracy and loss of effectiveness. Our control objective is to construct an adaptive fixed-time fault-tolerant controller to ensure that the system output tracks a desired trajectory within fixed time and the tracking error converges to a small area of zero whether the sensor faults occur or what kind of sensor faults take place. One of the characteristics of our proposed scheme is that its tracking time has no connection with the initial conditions of the system. Furthermore, as for unknown nonlinear functions, fuzzy logic systems are utilized to approximate them. And the complex calculation problem, which exists in the traditional backstepping method, has been dealt with by using the dynamic surface control technique. The proposed controller takes into account the reliability, rapidity, robustness and anti-interference of the system simultaneously, and the singularity problem in controller design is solved. In the end, the simulation results illustrate that the presented strategy is feasible and effective.

This article makes some efforts towards discussing the problem of observer design for a kind of discrete-time T-S fuzzy singular systems corrupted by process disturbances and measurement noises. To situate our design scheme in a more practical context, the premise variables of fuzzy systems under consideration are unmeasurable, and the process disturbances are only partially decoupled rather than completely decoupled. By integrating the fuzzy Lyapunov function method and the linear matrix inequality technique, an unknown input observer which can not only decouple partial process disturbances, but also attenuate the influence of measurement noises and non-decoupled process disturbances is proposed to achieve state reconstruction. Particularly, to reduce the conservatism, some slack matrices and scalars are utilized in observer design to obtain extra degrees of freedom. Finally, the performance of theoretical results is fully verified via two numerical simulations.
