“…On the other hand, the distributed consensus problem is associated with the behaviour of a set of agents, and then it is natural to think about how to achieve prescribed performance attributes for nonlinear MASs [28,29]. As an effective method to quantitatively describe the transient and steady-state responses of the controlled systems, the prescribed performance control has been gradually adopted in practical systems in recent years [30][31][32]. Among them, a state-feedback controller was developed to achieve preset performance attributes for the flexible joint robots [31].…”

In this paper, we consider the observer-based adaptive consensus tracking problem for a class of nonlinear time-delay multi-agent systems in the presence of input saturation. Under the assumption that the communication topology is directed and connected, a distributed adaptive consensus controller is developed based on the dynamic surface control technique. By constructing the nonlinear observer, the unmeasurable agents dynamics can be estimated. Input saturation problem is solved by a smooth function combined with an auxiliary variable. With the help of prescribed performance functions, the synchronization errors converge to the prescribed sets, which are characterized as a neighborhood of zero. According to Lyapunov stability theory, it is shown that with the proposed distributed consensus tracking approach, the consensus errors are cooperatively semi-globally uniformly ultimately bounded. Finally, a simulation example is provided to show the effectiveness of the proposed algorithm.

“…Among them, a state-feedback controller was developed to achieve preset performance attributes for the flexible joint robots [31]. In [32], an adaptive control approach was proposed to guarantee transient and steady-state performance of inverted pendulum system. However, these schemes are only suitable for single agent systems.…”

“…In this paper, a robust resilient control is proposed for parametric strict feedback nonlinear systems, which achieves prescribed output and virtual tracking performance and systemic function‐associated state bounds. With comparison to the controllers with constant and fixed control gains once implemented, the major contribution of this work lies in that a more robust and resilient control scheme by continuously nonlinear control gains is proposed, which endows the proposed control self‐adjusting ability using a nonlinear mapping function. Meanwhile, it is concluded that the proposed controller isolates the output prescribed performance from control gains selection .…”

Summary This paper investigates the robust resilient control problem for a class of parametric strict feedback nonlinear systems with prescribed output and virtual tracking errors performance. The resilience is governed by a continuously nonlinear control gains function, which endows the virtual and actual controllers with self‐adjusting abilities with respect to transformed error surfaces. The proposed control scheme is adaptation, estimation, and approximation‐free in the presence of unknown parameters and nonlinearities, and only a number of control gains, which is equal to the relative degree of the considered plants, need to be selected in applications. It is proved by rigorous analysis that the output tracking errors are confined in predefined prescribed performance functions under some nonrestrictive initial conditions, and the bounds of states are obtained characterized as control gains and systemic function‐associated constants. Finally, comparative illustrative examples are given to demonstrate the effectiveness of the proposed control scheme.

Summary This article studies the quantized event‐triggered adaptive tracking control problem for a type of switched nonlinear systems with parameter uncertainties, where the corresponding control problem for each subsystem can be unsolvable owing to vanishing control gains at some points. A constructive design scheme is established by triple design of quantized event‐triggered adaptive controller of each subsystem and a switching dynamic event‐triggering mechanism dependent on quantization and a hysteresis‐type state‐dependent switching law. The developed scheme handles not only the asynchronous switching between candidate event‐triggered adaptive controllers and subsystems, but also the asynchronous switching between candidate quantizers and subsystems. Both the switching law and the event‐triggering mechanism do not cause Zeno behavior. As a special case, a sufficient condition to address the quantized event‐triggered adaptive control problem for the switched nonlinear systems is also derived under dwell‐time switching. Finally, the effectiveness of the developed schemes are verified by a numerical example and a networked one‐link manipulator with motor dynamics.
