This paper is concerned with the observer design problem for a class of multi-input–multi-
output nonlinear systems with the unmodeled dynamics, unknown parameters and external …

Event-triggered control is aimed at monitoring the performance of dynamical control systems
through updating the control action only when the system needs attention. Its basic idea can …

This article concentrates on the event‐triggered adaptive tracking containment control
problem for a class of nonlinear multi‐agent systems (MASs) with unmodeled dynamics and …

This paper considers the problem of using a sampled‐data controller to globally stabilize a
class of uncertain upper‐triangular systems. First, we design a continuous‐time controller by …

In this paper, an adaptive neural-network-based tracking control strategy is proposed for a
class of nonlinear switched non-lower triangular systems with the completely unknown …

Unmodeled dynamics and output constraint are very often experienced in many physical
applications, while few studies on them simultaneously are constructed. This study …

We solve the problem of global uniform input-to-state stabilization of nonlinear switched
systems with time-varying and periodic dynamics, with dynamic uncertainties, and with …

In this paper, an underwater robot system with nonlinear characteristics is studied by a
backstepping method. Based on the state preservation problem of an Autonomous …

This paper focuses on the problem of adaptive control for a class of pure‐feedback
nonlinear systems with full‐state time‐varying constraints and unmodeled dynamics. By …

In this paper, an adaptive prescribed performance tracking control scheme is investigated for
a class of output feedback nonlinear systems with input unmodeled dynamics based on …
