“…Remark In some existing results (such as in References 21,23, and 24), the considered systems should be stabilizable, and the proposed control schemes may not ensure the stability of whole systems if there exist unstabilizable subsystems. In contrast, we develop a controller and the switching laws in this article, which can ensure the stability of the CLSs even if all subsystems are unstabilizable.…”

“…This article will deal with these problems. Main contributions are given as follows: Different from some existing literature, such as References 11‐15, a novel fault‐tolerant ETC method is driven for SNSs with actuator failures, which can reduce the WCRs effectively. Compared with some existing results, such as References 21,23, and 24, the proposed method has wider application range. There may exist unstabilizable subsystems in the considered SNSs.…”

SummaryIn this article, an adaptive fuzzy event‐triggered control problem of switched nonlinear systems with actuator failures under state‐dependent switchings is studied. Fuzzy logic systems are introduced to approximate the unknown nonlinear terms of the system. To reduce the wastage of communication resources, an adaptive fuzzy event‐triggered fault‐tolerant controller with a state‐dependent switching law is designed. Moreover, a modified hybrid switching law is also provided to avoid the fast switching phenomenon. In order to ensure the stability of the whole system, the convex combination technology and single Lyapunov function method are adopted. It is proved that all signals of the closed‐loop system are bounded. Finally, the effectiveness of the method is verified by simulation results.

“…In references [5][6][7][8][9][10], the tracking problems of nonlinear systems with output or state constraints have been studied by many scholars. Using the barrier Lyapunov function (BLF), the switching systems were studied in references [11][12][13][14]. In the literature [15], the authors proposed a BLF nested a shift function that allowed the systems output or states to satisfy the required systems constraints before exceeding a predetermined stabilization time.…”

In this paper, the problem of adaptive fuzzy tracking control for a class of uncertain switched nonlinear systems with unknown control direction is studied. Aiming at the problem, an adaptive control scheme with Nussbaum gain technology is constructed by using the average dwell time (ADT) method and the backstepping method to overcome the unknown control direction, and time‐varying asymmetric barrier Lyapunov functions (ABLFs) are adopted to ensure the full‐state constraints satisfaction. The proposed control scheme guarantees that all closed‐loop signals remain bounded under a class of switching signals with ADT, while the output tracking error converges to a small neighborhood of the zero. An important innovation of this design method is that the unknown control direction, asymmetric time‐varying full state constraints, and predefined time‐varying output requirements are simultaneously considered in uncertain switched nonlinear systems for the first time. We set a moment in advance, and make the systems comply with the constraint conditions before running the moment by the shift function nested in the first time‐varying ABLF. Finally, a simulation example verifies the effectiveness of the proposed scheme.

In this paper, for a class of uncertain fractional order chaotic systems with disturbances and partially unmeasurable states, an observer-based event-triggered adaptive fuzzy backstepping synchronization control method is proposed. Fuzzy logic systems are employed to estimate unknown functions in the backstepping procedure. To avoid the explosion of the complexity problem, a fractional order command filter is designed. Simultaneously, in order to reduce the filter error and improve the synchronization accuracy, an effective error compensation mechanism is devised. In particular, a disturbance observer is devised in the case of unmeasurable states, and a state observer is established to estimate the synchronization error of the master–slave system. The designed controller can ensure that the synchronization error converges to a small neighborhood around the origin finally and all signals are semiglobal uniformly ultimately bounded, and meanwhile, it is conducive to avoiding Zeno behavior. Finally, two numerical simulations are given to verify the effectiveness and accuracy of the proposed scheme.
