Extended Period Control Approach FCS-MPC for Three Phase …
4 天之前 · Finite control set model predictive control (FCS-MPC) selects a voltage vector state at fixed sampling period without the use of a modulator. As a direct consequence, the conventional implementation of FCS-MPC presents variable switching frequency. Period control approach (PCA-FCS-MPC) for a two-level three-phase inverter is effective in controlling the switching frequency without the need of ...
