Predictive Deadbeat Average Model Control for Power Conversion System With LCL Filter

IEEE Access, 2023
The inherent resonance issue of LCL filters in the power conversion system(PCS) will significantly degrade the system’s stability. Researches indicate that decreasing the time delay contributes to the system’s stability under converter-side

A novel deadbeat predictive current control of permanent magnet synchronous motor based on oversampling scheme

IET Electric Power Applications, 2021
When the speed of permanent magnet motor is relatively high, the fundamental frequency of stator voltage and current will rise. However, due to the limitation of switching frequency of power electronic devices, the switching times of power devices will ...

Deadbeat Predictive Current Control for Series-Winding PMSM Drive with Half-Bridge Power Module-Based Inverter

Energies, 2021
Series-winding topology (SWT) could improve the DC-link voltage utilization, as open-winding topology does. Meanwhile, it can greatly reduce the number of power devices. Firstly, for the half-bridge power modules (HBPMs)-based inverter, an N-phase series-

Luenberger Position Observer Based on Deadbeat-Current Predictive Control for Sensorless PMSM [PDF]

Electronics, 2020
Two problems can cause control performance degradation on permanent magnet synchronous motor (PMSM) systems, namely, fluctuation of PMSM parameters and the time delay between current sampling and command value update. In order to reduce the influence of these problems, a new current-predictive control strategy is proposed in this article for medium ...

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

Molecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...
