Design and performance analysis of hydraulic switching valve driven by magnetic shape memory alloy
Advances in Mechanical Engineering, 2021 In this paper, the hydraulic switching valve is designed and its dynamic performance is investigated through proposing a fast response actuator with magnetic shape memory alloy (MSMA) to drive the valve. MSMA actuator with spring return is designed and a

Designing redundant metering valves for hydraulic actuators under mixability and low cost-constraints [PDF]
, 2010 This article deals with the design of redundant metering valves for mechanically signalled hydraulic actuators. The final aim of the work is to manufacture a new low-cost valve in replacement of the existing expensive valve with an additional leakage ...

Development and Control of an Electro-Hydraulic Actuator System for an Exoskeleton Robot
Applied Sciences, 2019 Exoskeleton robots have been developed in various fields and are divided into electric and hydraulic exoskeletons according to the actuator type. In the case of hydraulic robots, because a unidirectional pump is applied, there are limitations to the ...

Crone control of a nonlinear hydraulic actuator [PDF]
, 2002 The CRONE control (fractional robust control) of a hydraulic actuator whose dynamic model is nonlinear is presented. An input-output linearization under diffeomorphism and feedback is first achieved for the nominal plant.
