Traditional electric excavator only uses the electric machine to replace the engine and
simulate its original working mode, which will not give full play to the advantages of the …

In this paper, an alternative method to predict the noise of a submersible Axial Piston Pump
(APP) for different valve seat materials is presented. The proposed method is composed of …

Since the energy crisis, the further development of a variable speed pump-controlled
hydraulic system driven by an electric machine has attracted increasing attention during the …

This paper deals with design and implementation of a real-time position control scheme
based on the synergistic combination of a recurrent neural network, an integral sliding mode …

Effective system identification is critical to realize the high-performance control of shaking
table, however, the common reduced-fidelity models can rarely capture the practical …

The centrifugal pumps usually work at various rotational speeds. The variation in the
rotational speeds will affect the internal flow, the external performance, and the anti …

Real-time flow estimation plays a vital role in multi-product pipeline operations, and the
accuracy of real-time flow estimation is affected by noise interference and instrument …

A hydraulic top drive is a high-power gyrator used in oil or scientific drilling rigs, whose shaft
is connected to drill pipe when it drives drilling tools to excavate well. The output speed of …

The article describes a new approach to the issue of controlling hydrostatic systems with
fixed displacement pump using the frequency inverter and the simple controller unit. The aim …

A remaining useful life (RUL) prediction method for an external gear pump is proposed by
Bayesian regularized radial basis function neural network (Trainbr-RBFNN). The variational …
