Over the last few decades, extensive use of flexible manipulators in various robotic
applications has made it as one of the research interests for many scholars over the world …

This article discusses the control design and experiment validation of a flexible two-link
manipulator (FTLM) system represented by ordinary differential equations (ODEs). A …

This paper presents an active disturbance rejection adaptive control scheme via full state
feedback for motion control of hydraulic servo systems subjected to both parametric …

In this paper, a model-based robust control is proposed for the polymer electrolyte
membrane fuel cell air-feed system, based on the second-order sliding mode algorithm. The …

In this paper, an output feedback nonlinear control is proposed for a hydraulic system with
mismatched modeling uncertainties in which an extended state observer (ESO) and a …

The methodology of ADRC and the progress of its theoretical analysis are reviewed in the
paper. Several breakthroughs for control of nonlinear uncertain systems, made possible by …

This paper proposes the adaptive extended state observer (AESO)-based active disturbance
rejection control (ADRC) to deal with the uncertainties, both in the plant and in the sensors …

The standard extended state observer based control (ESOBC) method is only applicable for
a class of single-input–single-output essential-integral-chain systems with matched …

Advanced manufacturing is characterised by machines that move an end effector through a
given trajectory to perform operations such as cutting, grinding and printing. In many …

This survey presents various methods of improving the overall estimation quality in the class
of extended state observers (ESO), which estimate not only the conventional states of the …
