“…Remark 7 In [18], the event-triggered decentralized control approach is designed for the interconnected nonlinear systems with unmeasurable states and input quantization. But the time delay and the actuator faults issues are not further studied in [18], while this paper is concerned with the eventtriggered decentralized FTC strategy for the interconnected nonlinear time delay systems with input quantization, unmeasurable states, and actuator faults. Hence, this paper could be regarded as the extension and supplement of [18].…”

“…In [17], an event-triggered tracking control scheme is proposed for interconnected systems with disturbances, it guarantees the robust stability with a given H ∞ disturbance attenuation level. Different from [17], which does not consider the input quantization problem, the authors in [18] propose an event-triggered decentralized control strategy, it could reduce the quantization error effects to the considered interconnected nonlinear systems.…”

“…The designed FTC strategy could guarantee the output signals of the considered interconnected systems could track the reference commands well and all signals of the closed loop systems are ultimately uniformly bounded. The main contributions of this paper are listed as follows (i) Compared with [18], [19], the model of the interconnected systems considered in this paper is more general. It not only includes unstructured uncertainties, unknown interconnected terms, unmeasurable states, but also includes unknown time delay functions and actuator faults.…”

In this study, the event-triggered decentralized fault tolerant control (FTC) problem is investigated for a class of interconnected nonlinear time delay systems in strict feedback form with input quantization and actuator faults. The model of interconnected nonlinear time delay systems includes unstructured uncertainties and unmeasurable states. Firstly, the radial basis function neural networks (RBFNNs) are introduced to identify the unstructured uncertainties and time delay functions. An adaptive RBFNNs state observer is constructed to identify the unmeasurable states, which will be used to the design of decentralized fault tolerant controller. By utilizing the adaptive backstepping technique with low pass filter, an event-based decentralized FTC strategy is developed for the considered interconnected nonlinear systems, such that the output signals could track the reference signals, and the stability of the closed loop systems is guaranteed. Finally, the effectiveness of the designed control strategy is illustrated by a practical simulation example.

This article investigates the adaptive output feedback control problem for a class of switched stochastic nonlinear systems via an event‐triggered strategy. By virtue of the dynamic gain technique, a novel event‐triggered adaptive output feedback controller is designed. It is proved that all states of the closed‐loop system are globally asymptotically stable in probability. Two examples are presented to verify the effectiveness of the proposed scheme.

This paper focuses on a decentralized adaptive scheme for a class of nonlinear time-varying interconnected systems based on neural networks for output tracking. By introducing constraint estimation method and two smooth functions, the barrier of unknown interaction in the system is avoided. By means of incorporating the back-stepping technique and the capability of neural networks, we aim to approximate the unknown nonlinear parts and establish a novel decentralized scheme with prescribed performance. Furthermore, according to Lyapunov stability theorem, it can be inferred that all variables of the controlled system are bounded, while the expected tracking converges to a compact set with a small error range. In addition, the simulation results verify that the proposed scheme can obtain a rapid learning effect.
