Protection and Control of Modern Power Systems, 2023 AbstractThis paper proposes a discrete space vector modulation and optimized switching sequence model predictive controller for three-level neutral-point-clamped inverters in grid-connected applications. The proposed strategy is based on cascaded model predictive control (MPC) for controlling the grid current while maintaining the capacitor voltage ...

Model predictive control with improved discrete space vector modulation for three‐level Vienna rectifier [PDF]
IET Power Electronics, 2019 This article proposes a model predictive control (MPC) with the discrete space vector modulation (DSVM) to reduce input current ripple of three‐level Vienna rectifier. The finite control set MPC (FCS‐MPC) applied in power converters has variable switching frequency and needs high sampling frequency for better input current quality.

Predictive Torque Control Based on Discrete Space Vector Modulation of PMSM without Flux Error-Sign and Voltage-Vector Lookup Table [PDF]
Electronics, 2020 The conventional finite set–predictive torque control of permanent magnet synchronous motors (PMSMs) suffers from large flux and torque ripples, as well as high current harmonic distortions. Introducing the discrete space vector modulation (DSVM) into the predictive torque control (PTC-DSVM) can improve its steady-state performance; however, the ...

IEEE Transactions on Power Electronics, 2019 This paper proposes the predictive control with the discrete space-vector modulation (DSVM) for Vienna rectifier connecting to the permanent magnet synchronous generator (PMSG) of the wind turbine system (WTS). Since Vienna rectifier has the special operation principle, Vienna rectifier generates only the feasible eight voltage vectors, which can be a ...

Finite Set Predictive Torque Control Based on Sub-divided Voltage Vectors of PMSM with Deadbeat Control and Discrete Space Vector Modulation [PDF]
2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019 The conventional finite set-predictive torque control (FS-PTC) of permanent magnet synchronous motor (PMSM) is known for its easy implementation, fast torque performance, and capability to include the constraints and nonlinearities. However, the most notable problems in the classical FS-PTC are the long calculation time and large current and torque ...
