Natural admittance control of an electro-hydraulic humanoid robot
2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014Compliant-motion control implementation on a humanoid robot with electrohydraulic joints is presented. Characterization results are shown, leading to a dynamic model used in feedback. A Natural Admittance Controller is designed, and its performance is demonstrated in demanding manipulation tasks, including dual-arm palmar manipulation of an egg and ...

Modeling and Control of Electro-Hydraulic Actuator
2019Modeling and position control of an Electro-Hydraulic Actuator (EHA) system is investigated in this paper. Linear ARX EHA system model is identified by taking the experimental data using system identification toolbox in the MATLAB/Simulink. From the identified models the best fit ARX 331 model is used to design a controller using fuzzy logic and ...

Robust Mu-Controller for Electro-Hydraulic Steering System
IEEE EUROCON 2019 -18th International Conference on Smart Technologies, 2019The paper presents the design of robust mu-controller for a laboratory test-bench composed of electrohydraulic-steering unit (EHSU), steering cylinder, 32-bit microcontroller, steering wheel and joystick. The controller design is based on an identified multivariable linear state-space model of the test-bench.

An Adaptive Control of an Electro-Hydraulic Position Control System
1984 American Control Conference, 1984In a hydraulic system input/output relation of the control valve is nonlinear and load dependent. An adaptive control would therefore be necessary for large changes in load parameter. The paper considers a position control system. This becomes a third order system under inertia load and with compressibility of oil considered.

Modeling and Control of an Electro-Hydraulic Poppet Valve
Fluid Power Systems and Technology, 2004This paper explores the dynamic modeling of a novel two stage bidirectional poppet valve and proposes a control scheme that uses a Nodal Link Perceptron Network (NLPN). The dynamic nonlinear mathematical model of this Electro-Hydraulic Control Valve (EHCV) is based on the analysis of the interactions among its mechanical, hydraulic, and electromagnetic
