Advantages of Pump Controlled Electro Hydraulic Actuators

Lecture Notes in Networks and Systems, 2021
Pump controlled hydraulic cylinders or Electro Hydraulic Actuators (EHA) have shown some advantages over common hydraulic systems and Electro Mechanical Cylinder (EMC) systems. EHA applications can be found in airplanes, submarines, mobile hydraulics, etc.

On Secondary Control Principles in Pump Controlled Electro-Hydraulic Linear Actuators

BATH/ASME 2020 Symposium on Fluid Power and Motion Control, 2020
Developments in the field of electro-hydraulic linear actuators controlled by variable-speed pump drives have been increasing over the past decade. The majority of these benefits from the speed control loops realized in the associated electric drives, hence these variable-speed pump drives have been operated as flow control units.

Using Leakage to Stabilize a Hydraulic Circuit for Pump Controlled Actuators

Journal of Dynamic Systems, Measurement and Control, Transactions of the ASME, 2013
Pump controlled hydraulic actuators offer higher energy efficiency than valve controlled actuators. However, there exists mode switching in pump controlled systems and instability may arise when a single rod cylinder is implemented. This paper examines the problem of system stability in a pump controlled system with single rod cylinders.

Control of Active Suspensions with Pump-Controlled Electro-Hydraulic Actuators under Uncertainties and Constraints using Adaptive Dynamic Programming

2020 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2020
This paper presents a novel control design for an active quarter-car suspension with pump-controlled electrohydraulic actuator (EHA) requiring only limited information about the pump-controlled EHA and considering constraints. The control design consists of two parts: force reference generation and force tracking. The force reference is determined by a
