An Improved FCS-MPC Based on Virtual Vector Expansion and Sector Optimization for 2L-VSCs

IEEE Access, 2022
Conventional finite control set model predictive control (FCS-MPC) outputs one voltage vector per period by vector traversal algorithm, which leads to low control accuracy, unnecessary high computational burden and unfixed switching frequency.
