Research on Fault Diagnosis Method of Electro-Hydrostatic Actuator [PDF]

Shock and Vibration, 2021
Electrohydrostatic actuator is a type of actuator that uses hydraulic energy as the energy transmission carrier, which has the advantages of small size and high power. Since it is commonly used in harsh conditions such as strong vibration, high pressure,

Design, Analysis, and Verification of an Electro- Hydrostatic Actuator for Distributed Actuation System [PDF]

Sensors, 2020
In order to provide a simplified and low-cost solution of the terminal for a distributed actuation system, this paper proposes an electro-hydrostatic actuator (EHA) based on the linear drive principle. The proposed actuator is directly driven by a linear

Delay Analysis and the Control of Electro-Hydrostatic Actuators

Applied Sciences, 2022
The electro-hydrostatic actuator (EHA) has a high energy density and a compact structure so it is widely used in all/more electric aircraft. To gain energy-saving capability, the hydraulic lock can be applied in the EHA system, which can overcome the ...

Bioelectric stimulation controls tissue shape and size [PDF]

Nature Communications
Epithelial tissues sheath organs and electro-mechanically regulate ion and water transport to regulate development, homeostasis, and hydrostatic organ pressure. Here, we demonstrate how external electrical stimulation allows us to control these processes

Active Load-Sensitive Electro-Hydrostatic Actuator for More Electric Aircraft [PDF]

Applied Sciences, 2020
In the flight control system, using an electro-hydrostatic actuator (EHA) instead of the currently used relatively mature electro-hydraulic valve-controlled actuator, there are three prevailing concerns, namely heating, size, and stiffness.

Thermal Characteristic and Analysis of Electro-Hydrostatic Actuator

IEEE Access
Electro-hydrostatic actuators (EHAs) are widely utilized due to their superior integration and high power-to-weight ratio. However, the elimination of a centralized oil source in EHAs restricts the cooling capacity of the system, leading to potential ...

Disturbance Observer-Based Sliding Mode Controller for Underwater Electro-Hydrostatic Actuator Affected by Seawater Pressure

Machines, 2022
This paper presents a disturbance-observer-based sliding mode control strategy for an underwater electro-hydrostatic actuator, particularly considering that electro-hydrostatic actuators (EHAs) significantly suffer from sea pressure disturbance, which ...
