In this paper, the high-performance tracking control of electromechanical servo systems is
concerned. A novel neural network state observer is designed to observe the unknown states. …

This paper designs a new observer to address the issue of disturbance rejection in
nonlinear plants with sense delay and measurement noise. The effect of sensor delay is …

This article examines the finite-time trajectory tracking control problem for a category of
nonlinear perturbed systems. A novel observation mechanism is constructed to mitigate the …

The output feedback active disturbance rejection control of a valve-controlled cylinder
electro-hydraulic servo system is investigated in this paper. First, a comprehensive nonlinear …

The extended state observer (ESO) is a vital component in feedback control design for
nonlinear systems. However, the presence of measurement delay in physical systems can …

To realize a high‐accuracy tracking control of an electromechanical actuator in which only
position signal is available, a new robust adaptive output feedback control strategy based on …

The progress of the design, synthesis, fluorescence properties and application of a new family
of fluorescent molecular switches towards information processing at the molecular level …

Based on the chemical‐sensitive fluorescence emission behaviors of the molecular switch 4‐bromo‐5‐methoxy‐2‐(2‐pyridyl)thiazole
(2‐BMPT), the communication of logic information …

Owing to their direct toxic effects on human beings, animals, and plants, chemical warfare
agents (CWAs) and their mimics have become widespread in chemical warfare and agriculture…

Three new polyoxometalates X 7 [PMo 8 O 30 ] (X=Na + , 1; K + , 2; NH 4 + , 3) have been
synthesized with the classical Keggin and/or Dawson heteropolymolybdophosphates and PCl …
