A small-scale electro-hydrostatic actuator, termed miniHydrA, was developed based on biomechanical requirements for gait and integrated into an ankle exoskeleton. The key advantage of this actuator concept lies in its compact size and the low mass of its

Enhanced Operation Mode Design and Motion Control of a Dual-Redundancy Electro-Hydrostatic Actuator
In dual-redundancy electro-hydrostatic actuators (EHAs), the dual pumps are mainly designed for safety, where the cylinder is controlled mainly by one pump while the other one is standby for redundancy. However, such a strategy is basically like a single-

A Qualitative and Quantitative Functional Modelling Method for PHM System Design
In the early stage of PHM system design, it is very important to analyse the failure modes and their effects,i.e. FMEA. A great number of model-based methods have been proposed recently; however, the analysis process might concern only qualitative or ...
