A Machine Learning Model of Electro-Hydrostatic Actuators With the Low-Data Limit and Its Application to Fault Detection

IEEE Access
This paper presents a novel approach for modeling the dynamics of electro-hydrostatic actuators (EHAs) using the sparse identification of nonlinear dynamics (SINDy) algorithm. SINDy is a machine learning algorithm that identifies governing equations from

Enhanced Operation Mode Design and Motion Control of a Dual-Redundancy Electro-Hydrostatic Actuator

Actuators
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-
