This paper is concerned with the leader-following consensus problem for a class of Lipschitz
nonlinear multi-agent systems with uncertain dynamics, where each agent only transmits its …

This paper proposes a novel Neural Network Adaptive Observer (NNAO) for Nonlinear
Systems with Partially and Completely Unknown Dynamics (NSPCUD), subject to variable …

Robust trajectory tracking problem is dealt with for the under-actuated quadrotor system,
which is decomposed into two subsystems, ie, the inner-loop rotational subsystem perturbed …

Because of their advantages, speed sensorless induction motor drives have received a lot of
attention in the academic and industrial communities over the last decade. Despite the …

In this paper, a sampled delayed output extended state observer-based adaptive feedback
controller (SDOESO-AFC) is proposed for robot manipulators under complex conditions with …

This paper proposes a state observer with a cascade structure for a class of nonlinear
systems in the presence of uncertainties in the state equations and an arbitrarily long delay …

The state reconstruction problem for a remote robotic system with communication delay is
investigated in this paper. A symmetric estimation scheme is proposed based on both input …

This paper presents the design of a high-gain nonlinear observer for bilinear systems in the
block form. We prove the uniform exponential stability of the observer error by finding a …

The design of distributed observers is a hot topic in the research of multi-agent system. It can
estimate the whole states of the plant with only portion of output information and the …

This paper addresses the problem of estimating oxygen excess in proton exchange
membrane fuel cells (PEMFC) systems. Indeed, poor management of the air supply system …
