Finite-Set Model-Predictive Control Strategies for a 3L-NPC Inverter Operating With Fixed Switching Frequency
TL;DR: Two finite-set model-predictive control methodologies for a grid-connected three-level neutral-point-clamped converter are investigated and show a good performance, in steady-state and transient response, with a total harmonic distortion lower than $\text{2}\%$ for the currents supplied to the grid.
Journal ArticleDOI
Model Predictive Torque Control for Torque Ripple Compensation in Variable-Speed PMSMs
TL;DR: A hybrid method that uses the output information from an observer and look-up table is presented to obtain a good cogging-torque estimation and thus an accurate mitigation of this disturbance torque at low rotational speed.
Journal ArticleDOI
Control of Wind Energy Conversion Systems Based on the Modular Multilevel Matrix Converter
Matias Diaz,Roberto Cardenas,Mauricio Espinoza,Felix Rojas,Andres Mora,Jon Clare,Patrick Wheeler +6 more
TL;DR: The proposed control strategies enable decoupled operation of the converter, provide maximum power point tracking capability at the generator side, grid code compliance at the grid side (including low-voltage ride-through control) and good steady state and dynamic performance for balancing the capacitor voltages in all the clusters.
Journal ArticleDOI
Computationally Efficient Cascaded Optimal Switching Sequence MPC for Grid-Connected Three-Level NPC Converters
Andres Mora,Roberto Cardenas-Dobson,Ricardo P. Aguilera,Alejandro Angulo,Felipe Donoso,Jose Rodriguez +5 more
TL;DR: A model predictive control strategy based on optimal switching sequence concepts is proposed for a grid-connected three-level neutral-point clamped converter that optimally controls both the grid currents and the capacitor voltages even during disturbances and large step changes in the references.
Journal ArticleDOI
Control Scheme for an Induction Motor Fed by a Cascade Multicell Converter Under Internal Fault
TL;DR: The transient operation from normal to faulty operation when such voltages are used and an induction motor is driven by the converter is presented, showing a significant improvement on the signal behavior.
