“…14 So an integral sliding mode control (ISMC) scheme is proposed and well developed, which can eliminate the reaching phase needed in a conventional SMC strategy. 15,16 Wang et al 15 proposed a novel event event-triggered ISMC strategy for higher-order multi-agent systems subject to external disturbances. In Yang et al’s 17 study, based on the ISMC and a designed disturbance observer (DO), a novel control scheme is presented to reduce chattering and exhibit the properties of nominal performance recovery.…”

This brief proposes a novel composite observer-based integral sliding mode tracking control algorithm for a class of nonlinear systems affected by both actuator faults and mismatched disturbances. First, different types of observers, including the extended state observer, the fault diagnosis observer, and the disturbance observer, are integrated to estimate the unknown system state, actuator faults, and mismatched disturbances timely. Then, in accordance with the estimation information, the integral sliding surface and the integral sliding mode controller are proposed, which can tolerate the actuator faults and reject the mismatched disturbances. Meanwhile, the state trajectories can be driven into the specified sliding surface in a finite time. Furthermore, not only the stability, but the favorable dynamical tracking and the output constraints of closed-loop augmented systems can be guaranteed. Finally, the validities of the proposed algorithm are embodied by the simulation results of typical A4D systems.

“…Remark 2. Compared with the event-triggered mechanism in [20,22], the controller proposed in this paper does not require information about communication topology and is fully distributed, which implies a wider range of applications. Moreover, the proposed event-triggered controller can manage the uncertainties, which is not considered in [20].…”

This paper investigates the distributed time-varying formation (TVF) problems for general linear multi-agent systems (MASs) subject to matched bounded uncertainties based on an adaptive event-triggered mechanism. A TVF protocol was designed with an event-triggered mechanism by introducing adaptive weights into the formation control protocol and triggering condition, and the large chattering phenomenon was avoided by the σ-modification adaptive law. According to the Lyapunov stability theory, proof has been established that the MASs in the presence of uncertainties can realize the expected formation that satisfies the given feasible condition. Finally, an example is provided to verify the effectiveness of the proposed algorithm.

“…For instance, Li et al in [11] considered a distributed consensus problem of linear heterogeneous multi-agent systems subject to different matching uncertainties and designed a fully distributed continuous adaptive consensus protocol. An event-triggered integral sliding mode control strategy was proposed in [30] to solve the time-varying formation problem for higher-order multi-agent systems which suffer from disturbances. By the Nussbaum-type gain technique and the function approximation capability of neural networks, an adaptive neural networks-based controller for the higher-order nonlinear multi-agent system with a fixed topology was designed in [26].…”

“…The main contributions of the paper can be summarized as follows: (1)A higherorder nonlinear multi-agent system with unmatched disturbances is considered. There have been several meaningful anti-disturbance control algorithms for multiagent systems with disturbances in [11,30,26,28]. However, these literatures only consider matched disturbances.…”

In this paper, the distributed consensus problem is investigated for a class of higher-order nonlinear multi-agent systems with unmatched disturbances. By the back-stepping technique, a new distributed protocol is designed to solve the consensus problem for multi-agent systems without using the information of the Laplacian matrix and Lipschitz constants. It is proved that the practical consensus of multi-agent systems with unmatched disturbances can be achieved by the proposed protocol. Finally, the validity of the proposed scheme is verified by a simulation.
