In this paper, a novel robust backstepping control strategy is introduced to achieve high‐
accuracy tracking performance for electro‐hydraulic servo systems (EHSSs) without velocity …

This paper aims to improve the tracking control performance of the three-stage valve (TSV)
controlled electro-hydraulic servo system (EHSS) with parameter uncertainties and other …

This paper presents the design of an adaptive fast-finite-time extended state observer for
electro-hydraulic actuator systems. First, the system model is divided into three parts, and …

In this paper, a practical output feedback disturbance rejection controller holding the desired
dynamic behavior is proposed for precise movement control of hydraulic systems with …

For a propulsion system with dead-zone, time-varying parameters and sudden disturbances,
the existing hybrid control methods based on sliding-mode and extended state observer still …

In this paper, a disturbance observer-based backstepping tracking control is designed for an
electro-hydraulic actuator (EHA) system to estimate and track reference signals in a finite …

The electro-hydraulic servomechanism is widely used in marine vehicles due to its higher
power density. However, the servomechanisms suffer from serious throttling loss which …

Investigation of friction force induced by seals is important in improving control accuracy and
evaluating sealing performance for hydraulic actuators. An experimental apparatus was …

In this paper, a novel finite-time nonlinear extended state observer (NLESO) is proposed
and employed in active disturbance rejection control (ADRC) to stabilize a nonlinear system …

In this paper, an active disturbance rejection control is designed to improve the position
tracking performance of an electro-hydraulic actuation system in the presence of parametric …
