VS-ACC applied to a hydraulic actuator

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
In this paper a complete stability proof of a cascade controller applied to a hydraulic actuator is presented. To deal with the mechanical and hydraulic uncertainties an adaptive and a variable structure control law are combined. The theoretical approach may be generalized to the case of hydraulically driven manipulators. An experimental implementation

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 ...

Intelligent Diagnostic System for Hydraulic Actuator

2019 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2019
© 2019 IEEE. The proposed technical solution allows optimizing the process of hydraulic drive control, which leads to increased energy efficiency, as well as diagnosing the state of the hydraulic system of the industrial machine. To ensure the speed of the process of diagnosing the state of the hydraulic drive in addition to the hardware of the system,

Cascade control of hydraulically actuated manipulators

Robotica, 1990
SUMMARYA fundamental study on the control of hydraulically actuated robots is presented. Dynamic modelling is performed in both time-domain and frequency-domain. It is shown that the inclusion of hydraulic elements increases the order of the system. Hydraulic compliance is the most effective factor in this regard.Three distinct control strategies are ...

Leg mechanisms for hydraulically actuated robots

2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009
The performance of highly dynamic robotic machines is directly associated with both the actuation means and the specific mechanical properties/configuration of the system. Hydraulic actuation demonstrates significant competitive advantages when minimum weight and volume, large forces and wide range of speeds are required and this makes it very suitable

Hydraulic actuators in application of robot manipulator

2012 IEEE International Conference on Automation Science and Engineering (CASE), 2012
Application of hydraulic actuators to robotic systems has different areas where electric motor system cannot be used. High bandwidth together with high force and torque make the system smaller and faster. Some examples are introduced made by KNR systems Inc.

Analysis for the power loss of electro hydrostatic actuator and hydraulic actuator

2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015
This article describes the difference between traditional airborne hydraulic actuator and electro hydrostatic actuator in heat dissipation. The power loss of the two systems are analyzed based on the method of energy transfer under different working conditions.

Applications of electro-hydraulics actuators

SoutheastCon 2016, 2016
Electro-hydraulic systems can be used in robust robotics systems that have to carry heavier loads efficiently. Electrical drives have proven to be reliable and easy to control, but they may have problems when it comes to holding a position under load for a long period of time.

Transputer control of hydraulic actuators and robots

IEEE Transactions on Industrial Electronics, 1996
The paper reports and discusses results from a Danish mechatronic research program focusing on intelligent actuators for intelligent motion control. A mechatronic test facility with a transputer controlled hydraulic robot suitable for real-time experimentation and evaluation of control laws and algorithms is described.
