Improved Deadbeat Predictive Direct Power Control for Three-Phase PWM Rectifier Based on LADRC

In modern marine vessels equipped with electric propulsion systems, rectifiers are commonly used as part of the setup. However, the conventional deadbeat predictive direct power control strategy for three-phase voltage source pulse-width modulation (PWM)

LADRC‐based non‐characteristic harmonic suppression strategy for pumped storage power plants

The static frequency converter (SFC) in a pumped storage power plant often causes harmonic problems in the dragging processes, which may lead to the false operation of automatic devices in the power station, and even damage to the power equipment.

A Novel Grid-connected Current Harmonics Control Method of Single-phase Distributed PV with Nonlinear Local Loads Based on LADRC

, 2018
Most traditional single-phase photovoltaic (PV) grid-connected inverters only operate at unity power factor, which is ineffective for the current harmonics generated and injected into the grid by local non-linear loads.

Frequency Modulation Control of Grid-Forming Converter Based on LADRC-MI

The increasing proportion of new energy in the power system leads to a decrease in system inertia and weakens the frequency stability of the system. The use of grid-forming (GFM) control for inverters is an effective method to improve frequency stability
