This paper deals with the global asymptotic stabilization problem for discontinuous nonlinear time‐varying switched systems in the sense of fractional‐order. Via the designed periodic switching law, some criteria are firstly developed. It is shown that the derivatives of the constructed Lyapunov functions are allowed to be indefinite. Several corollaries are further derived, and some existing results can be regarded as special cases of our obtained results. Finally, our findings are verified by three numerical examples and one experiment.

“…Moreover, the event‐triggered control (ETC) method is also employed to SNSs. The authors in References 19‐23 investigated the problem of event‐triggered adaptive fuzzy control for SNSs based on CLF method. The problem of event‐triggered finite‐time control for uncertain SNSs was studied in Reference 19.…”

“…In Reference 22, an adaptive fuzzy ETC scheme was developed for SNSs with dead‐zone nonlinearity. In Reference 23, an event‐triggered tracking controller was proposed for uncertain pure‐feedback SNSs. In References 24‐27, the problem of event‐triggered adaptive fuzzy control for SNSs based on MLF method was studied.…”

“…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.

“…To estimate a torque disturbance, initially, a nonlinear disturbance observer (NDO) is developed in Reference 24 for a nonlinear robotic manipulator. Recently, Jeong and Yoo 25 devised an event‐triggered tracker via NDO in the presence of switched non‐affine nonlinearities. It should be emphasized that developing NDO necessitates previous knowledge of disturbances, which is frequently unavailable or may alter depending on operational conditions.…”

This article focuses on the concerns of a tracking control and active disturbance rejection for nonlinear switched systems described by Takagi–Sugeno fuzzy framework with state‐dependent nonlinear perturbations, actuator saturations and disturbances. Especially, a nonlinear equivalent‐input‐disturbance technique is employed to guarantee that only the external disturbances are rejected while retaining the beneficial nonlinearity of the system. Notably, with the aid of the lifting technique, the modified repetitive control are accurately described by a continuous‐discrete two‐dimensional model is designed to improve the tracking precision. The fuzzy‐membership‐function‐dependent piecewise Lyapunov–Krasovskii functional (LKF) by exploiting the knowledge of the membership functions are built to assure the exponential stability of the investigated system. Moreover, the controller and observer gains can be obtained as solutions to a set of strict linear matrix inequalities. Finally, an application example based on the cognitive radio model is given to verify the efficacy of the proposed control protocol.
