Electronics for electro-hydraulic actuation system

2015 IEEE 21st International Symposium for Design and Technology in Electronic Packaging (SIITME), 2015
The electro-hydraulic actuation system was designed and realized by INOE 2000 - IHP for Regional Air Services - Tuzla Airport. It is used on the Cabin Emergency and Escape Trainer CEET B732 for the Sea Survival School. The closed loop control system controller, that implements the actuation system functionality, was designed as a software application ...

Soft gripper actuated by electro-hydraulic force

Electroactive Polymer Actuators and Devices (EAPAD) XXI, 2019
In this paper, we propose a soft robotic gripper to be mounted easily and to have high actuation force by harnessing electrostatic and hydraulic phenomena. Specifically, we develop a soft actuator to consist of swelling pouches, a silicon backbone beam, and a supplying pouch with electrodes on its both surfaces. The two pouches include dielectric fluid,

ANFIS modeling of electro-hydraulic actuator system

2012 IEEE 8th International Colloquium on Signal Processing and its Applications, 2012
Precise control of electro-hydraulic actuator (EHA) system has been an interesting subject due to its nonlinearities and uncertainties characteristics. Good control can be designed when precise model of the system is available. ANFIS (Adaptive Neuro-Fuzzy Inference System) modeling technique has proven to be able to model various nonlinear systems. The

Experimental Verification of An Electro-Hydraulic Actuation System Driven by An Integrated Electro-Hydraulic Unit

International Journal of Fluid Power, 2023
This paper proposes an electro-hydraulic actuator (EHA) system, and a novel-designed electro-hydraulic unit (EHU) consisting of a fixed-displacement hydraulic gear machine and a variable-speed electric machine. The novel EHU design integrates an electric machine and a hydraulic machine in a single housing, targeting optimal compactness, power density ...

Fractional-order model identification for electro-hydraulic actuator

2015 10th Asian Control Conference (ASCC), 2015
Hydraulic actuator has been commonly applied in industrial application owing to its fast response and capability to handle heavy load. Good system identification for hydraulic is necessary in order to understand the system so that further action such as control design can be implemented.

Electro-hydraulic actuation of primary flight control surfaces

IEE Colloquium on All Electric Aircraft, 1998
Increasingly demanding performance and certification requirements for next-generation aircraft flight control systems, together with a continuous development effort within the industry towards 'all/more electric' aircraft, have fostered the need to replace traditional hydraulic actuation systems by electric and/or electro-hydraulic technology ...

Tracking control for electro-hydraulic actuator using ZPETC

2011 IEEE Control and System Graduate Research Colloquium, 2011
Hydraulic actuator is widely used in industrial applications because it exhibits linear movements, fast response, smooth reversal and accurate positioning of heavy load. The torque to inertia ratio is also large which resulting high acceleration capability. Reducing the position tracking error of the hydraulic system is a very challenging task.

CHAOTIC TRAJECTORY TRACKING FOR AN ELECTRO-HYDRAULIC ACTUATOR

IFAC Proceedings Volumes, 2006
Abstract Various robust control techniques such as Integral Block Control, Sliding Mode Control and H-infinity Control are combined to design a controller, forcing an electro-hydraulic actuator driven by a servovalve to track a chaotic reference trajectory.

Modeling and identification of an Electro-Hydraulic Actuator

2016 12th IEEE International Conference on Control and Automation (ICCA), 2016
In this work, a physical non-linear model of an Electro-Hydraulic Actuator has been developed. Each system component (valves, pipes, cylinders) and their interactions have been modeled by means of conservation and constitutive laws. The actuator dynamics, with lumped-parameter element models, have been treated accurately, with special attention given ...
