Sensorless Speed/Torque Control of DC Machine Using Artificial Neural Network Technique

open access: yesTikrit Journal of Engineering Sciences, 2016
In this paper, Artificial Neural Network (ANN) technique is implemented to improve speed and torque control of a separately excited DC machine drive. The speed and torque sensorless scheme based on ANN is estimated adaptively.

A novel three-level optical storage machine based on grid frequency control

open access: yesXi'an Gongcheng Daxue xuebao, 2023
Due to the fluctuation of PV power, it is difficult to keep the active power of the PV grid-connected inverter constant. To address the above problems, this paper proposed a new three-level integrated photovoltaic storage machine consisting of a T-type ...

Machine learning-based prediction of a BOS reactor performance from operating parameters [PDF]

open access: yes, 2020
A machine learning-based analysis was applied to process data obtained from a Basic Oxygen Steelmaking (BOS) pilot plant. The first purpose was to identify correlations between operating parameters and reactor performance, defined as rate of ...

Melt conditioned direct chill casting (MC-DC) of wrought Al-alloys [PDF]

open access: yes, 2008
Melt Conditioned Direct Chill (MC-DC) casting is a new development for producing high-quality billets and slabs. In the MC-DC process, liquid metal is continuously fed into a MCAST (melt conditioning by advanced shear technology) machine, where the ...

A Common DC-Bus-Configured Traction Motor Emulator Using a Virtually Isolated Three-Phase AC-DC Bidirectional Converter

open access: yesIEEE Access, 2021
An industrial drive testing, with a ‘real-machine’ can pave way, for some serious issues to test-bench and motor. A slight disturbance in control logic amid testing, can damage the physical machine or drive.
