Abstract:
Recently, the use of smart material–based electro-hydrostatic actuators is increasingly becoming more attractive to overcome the inherent disadvantages of conventional actuation systems and to offer new opportunities for performance improvement. A new type of a dual magnetostrictive material rods–based electro-hydrostatic actuator is presented in the current study. An active rotary rectification valve is utilized to convert small, high-frequency vibration displacements of the magnetostrictive material rods into continuous, smooth and bidirectional motion of a hydraulic cylinder by fluid rectification. Simulation and experiments were performed to confirm the feasibility of the new concept. The experimental results indicate that the dual magnetostrictive material rods–based electro-hydrostatic actuator exhibits a maximum flow rate that is approximately twice that of a single magnetostrictive material rod–based electro-hydrostatic actuator, and that the operating frequency increases from 110 to 150 Hz.

Abstract:
Hydraulic actuators play a major role in aircraft flight actuation and control. Primary control systems in an aircraft typically control the components that guide an airplane during flight. Electro Hydrostatic Actuators (EHA) is emerging as a viable option for aerospace as well as industrial machine builders. It is an emerging technology which replaces centralized hydraulic system by a self-contained and localized direct drive actuator system. As most of the aircraft applications use symmetric actuator, Symmetric actuator EHA system configuration is considered in most of the literatures. However in case of many industrial applications, asymmetric actuators are being used. The dynamic response that means how fast an actuator reaches a target position is an important criteria for any application. An indigenous experimental setup of EHA system is developed with measuring instruments and sensors that forms a mechatronic system. The Variable Motor and Fixed Pump configuration of EHA is used for experimentation. In this work the load analysis is carried out on asymmetric and symmetric actuators. Similarly the load analysis is carried out on different controllers like Proportional Derivative (PD), Proportional Integral (PI) and Proportional Integral Derivative (PID) over the dynamic response as a output. It is found that symmetric actuator and PD controller gives better results.

Abstract:
Smart material–based electro-hydrostatic actuators are a potential alternative to traditional hydraulic actuators. Piezoelectric materials are a type of smart materials that can deliver large blocked forces. In this article, a piezoelectric stack–based electro-hydrostatic actuator is first introduced by presenting the schematic diagrams of its structure and work principle. Next, according to the research of the piezoelectric stack–based electro-hydrostatic actuator working principle, a mathematical model that can describe the dynamic characteristics of piezoelectric stack–based electro-hydrostatic actuator was established. The output displacement model of the piezoelectric stack–based actuator was established based on the improved asymmetric Bouc–Wen model. The simulation model was built in MATLAB/Simulink. Finally, experiments under different working conditions were conducted, as well as the corresponding simulations. The experimental results demonstrate that the prototype no-load output flow reaches its maximum at 275 Hz and the output flow peak is close to 1.6 L/min. Moreover, the load capacity is more than 20 kg and the maximum load is more than 50 kg according to the trend forecast. The simulation results exhibit good agreement with the experimental results, which means that the piezoelectric stack–based electro-hydrostatic actuator model is feasible.

Abstract:
More-electric aircraft draws considerable attention due to its high efficiency, high reliability, and easy maintenance. Linear electro-hydrostatic actuator is a novel linear actuation system suitable for more-electric aircraft, and offers many advantages over traditional rotary electro-hydrostatic actuator. However, it requires high-frequency reciprocate actuation of linear oscillating motors with both high efficiency and high power factor. In this study, a novel moving-magnet tubular linear oscillating motor with dual-resonance is proposed for linear electro-hydrostatic actuator applications to achieve high efficiency and high power factor simultaneously. Firstly, system impedance model is set up analytically, which helps to analyze the influence of structure parameters on system performance. Based on this model, working efficiency and power factor are compared with the nonresonance design, and validated by experimental results. In order to take real scenario into considerations, the nonlinearity of motor and rectangular-type load is also analytically derived and analyzed with effective resonant frequency tracking method proposed. It shows that dual-resonance design does increase system efficiency and power factor, and can be applied in linear electro-hydrostatic actuator system for more-electric aircraft effectively.

The paper proposes a novel dual-redundancy motor pump for the electro-hydrostatic actuator. Rather than the traditional single motor pump electro-hydrostatic actuator system, the system proposed in this paper can operate in three working modes and automatically adjust its operating condition in accordance with task requirements. The novel dual-redundancy electro-hydrostatic actuator system prototype was developed, and a high-performance control method was proposed and applied to the system, combining proportional–integral–derivative and sliding mode control to study the control strategy and implementation method of double closed loop. In addition, a physical model simulation was conducted on the basis of Amesim for this electro-hydrostatic actuator under several working conditions. Results showed that the dual-redundancy electro-hydrostatic actuator can decrease power loss and demonstrate excellent performance and reliability.

Abstract:
This paper describes control methods of an Electro-Hydrostatic Actuators (EHA) for an exoskeletal power-assist systems. By increasing backdrivability of the electro-hydrostatic actuators, the exoskeletal power-assist systems can achieve haptic interaction with a human. We propose a pressure feedback controller based on singular perturbation method, which is used in a power-assist controller of the exoskeletal power-assist system. The controller assists human movements by increasing the sensitivity of the electrohydrostatic actuator with estimated torque feedback. The controllers were implemented on an exoskeletal power-assist system for a knee joint with an electrohydrostatic actuator. Their efficacy was evaluated by experiments.

Abstract:
In recent years, power by wire (PBW) technique is developed in the European and American aviation field, and one of its important bases is electro-hydrostatic servo technique. In this paper, speed controlled and displacement controlled electro-hydrostatic actuation systems are modeled and simulated, by comparing their Bode graphics and time-zone respond curves, which shows that displacement control has small load inertia and high gain, so its dynamic performance is better. Thus, conclusion can be drawn that speed-displacement composite control may indeed improve the dynamic performance of electro-hydrostatic actuator.

Abstract:
Purpose The purpose of this paper is to provide a new hydrostatic actuator controlled by a piezoelectric piston pump and to reveal its characteristics. Design/methodology/approach In this paper, a piezoelectric pump with passive poppet valves and hydraulic displacement amplifier is designed as a new control component in a hydrostatic actuator for high actuation capacity. A component-level mathematical model is established to describe the system characteristics. Simulation verification for cases under typical conditions is implemented to evaluate the delivery behavior of the pump and the carrying ability of the actuator. Findings By using the displacement amplifier and the passive distributing valves, simulation demonstrates that the pump can deliver flow rate up to 3 L/min, and the actuator controlled by this pump can push an object weighing approximately 50 kg. In addition, it is particularly important to decide a proper amplification ratio of the amplifier in the pump for better actuation performance. Originality/value The piezoelectric pump presented in this paper has its potential to light hydrostatic actuator. The model constructed in this paper is valid for characteristic analysis and performance evaluation of this pump and actuators.

Abstract:
A novel Electro-Hydrostatic Actuator (EHA) prototype – designed to operate on subsea gate valves in deep and ultra-deep water – is analysed and qualified in terms of functionality under design and normative constraints. The prototype is assembled in a test bench for load control in a hyperbaric chamber where the high subsea environmental pressure can be emulated. The process variables under evaluation are monitored through a set of pressure and position sensors, which are part of the prototype design. The experimental results demonstrate a robust behaviour of the actuator concerning the imposed external pressure and load forces even with a forced limitation in its power input. Moreover, the prototype performs consistently throughout the entire endurance trial, asserting high reliability. With the results obtained, the subsea EHA concept is effectually eligible to a technology readiness level 4, according to the API 17N.

Abstract:
In some industrial fields, such as aerospace, electro-hydrostatic actuators (EHAs) are increasingly used to replace conventional standard hydraulic actuators due to their better energy performance. Moreover, implementing different type or technology of actuators in redundant actuation systems working on the same moving part introduced some new challenges. This paper presents a force-tracking controller for an asymmetric electro-hydrostatic actuator that is submitted to an external motion generated by an external source. In this case, the rod displacement is considered as an external disturbance for the hydraulic cylinder, but it is assumed that this disturbance can be easily measured using sensors. The theoretical motivation of this work is discussed along and a variable gain state feedback control based on Linear Parameter Varying control (LPV) theory is proposed to achieve stability, disturbance rejection and tracking performance. The Linear Matrix Inequalities (LMI) framework is used to determine a control law including an augmented state feedback with an integral action that reduces trajectory-tracking errors. Simulation results of the control law are finally given to verify the global performance of this control design.

Abstract:
Currently the system development of aircraft engineering concentrates its focus on the reduction of energy consumption more than ever before. As a consequence, the efficiency of subsystems inside the aircraft is highlighted. According to previous investigations the simplification/unification of conventional multifaceted board energy systems by means of electric power management is the most promising way concerning aircraft global efficiency improvement. The main aim of the present work was to optimize a multi-device, heavy duty EHA-System by introducing of a comprehensive perspective. In order to achieve the final, non-plus-ultra improvement level, the attributes of architecture, hardware and operation method were combined in an interactive manner, whereas particular attention has been paid to the mutual enhancing influences. The maximum reduction of losses, the minimizing of consumption and weight optimization can be achieved concurrently when the physical coherences between the involved subsystems are understood and their hidden potentials are exploited. This can only be achieved in one way and the detail follows: The most effective way to reduce both manufacturing effort and weight is to introduce a multiple-allocation philosophy. The highest reliability possible can be achieved by novel cascade-nested system architecture and strict restraining of the control logic. By employing an ultra-low-loss hardware concept, the energy efficiency can be maximized at a necessary minimum own weight. Last but not least, possibly the most important cognition is that an intelligent operation method will improve the actual system and influence the entire system positively and with a lower effort. The final conclusion is that the only and reasonable way to achieve an ultimate optimized solution of an actuation system is an all-encompassing consideration. Eventually it was to recognize that the final result is nothing but ultimate lightweight architecture, i.e. a non-plus-ultra solution.
Gegenwärtig konzentriert sich die Technologieentwicklung für Flugzeuge auf die Reduktion des Energieverbrauchs mehr denn je zuvor. Hierfür ist die Effizienz der an Bord befindlichen, nicht propulsiven Subsysteme neben der Wirkungsgradverbesserung der Triebwerke von zentraler Bedeutung. Laut vorangegangenen Untersuchungen und Studien ist die Vereinfachung bzw. Vereinheitlichung der Vielfalt der konventionellen Bordenergiesysteme durch ein adäquates Energiemanagement unter Verwendung von Elektrizität der aussichtsreichte Weg zur Effizienzverbesserung auf der Gesamtflugzeugebene. Durch die Elektrifizierung wurden die einzelnen Geräte zwar zuverlässiger und energieeffizienter als je zuvor aber gleichzeitig erheblich schwerer, sodaß ein signifikanter Verlust an Nutzlasten auf Gesamtflugzeugebene hervorgerufen wird. Das Hauptziel der vorliegenden Arbeit war es, ein Schwerlast-EHA-System mit mehrfachen Betätigungseinheiten durch Einführung von umfassenden Perspektiven zu optimieren. Durch Einführung der sog. ganzheitlichen Leichtbauweise demonstriert die Arbeit, wie das Subsystem mit mehreren Endgeräten ultimativ optimiert werden kann, ohne Abstriche an Gewichtsbilanz u/o Kompromiß mit der Energieeffizienz zu machen. Um eine wahrhaftige Optimierung, d.h. die Erreichung des ultimativen, Nonplusultra-Verbesserungslevels zu erreichen, wurden die Systemarchitektur, die Hardware und die Operationsmethode interaktiv kombiniert, wobei die besondere Aufmerksamkeit auf die interaktiven, zur Verbesserung führenden Einflüsse gelegt wurde. Die Minimierung des Energieverbrauchs und die ultimative Gewichtsoptimierung gleichzeitig können erreicht werden, wenn die physikalischen Zusammenhänge zwischen den involvierten Subsystemen verstanden und ihre verborgenen Potentiale ausgenutzt werden. Der einzige und vernünftige Weg zur Erreichung der ultimativen Optimierung eines Betätigungssystems ist eine allumfassende Betrachtung, also eine ganzheitliche Betrachtungs- bzw. Vorgehensweise.

Abstract:
Recent Power On Demand approaches, realized by using speed and/or displacement variable pump units, led to a significant increase of energy efficiency on hydraulic forming presses. In this paper we follow up on this development by laying the focus on the energy management and storage design of such machinery. With a derived fluidtronical model, we compare five different topologies that supply and manage the power flow for a forming press with die cushion. Our evaluation criteria are: energy consumption, minimization of the infeed power, and qualitative costs. For a representative forming cycle, the losses occurring on each of the drivetrain components and the power electronics accessory are derived in detail. We expect that this research will lead to deeper investigation of more intelligent energy management systems that use multiple storages in an optimal way and further learn and adapt during operation.
