Finite control set model predictive control (FCS-MPC) chooses at each sampling period the input control vector state without using a modulator. Therefore, it belongs to the direct control family. As a consequence, the conventional implementation of FCS-MPC presents variable switching frequency. This makes difficult the design of the output filter. This article investigates the period control approach (PCA-MPC) to achieve a fixed switching pattern, similar to that of modulated strategies placed at a desired frequency. PCA-MPC cannot reach a reference switching frequency without a steady-state error. Nonetheless, it is more than capable of reaching a fixed switching pattern, with clean spectrum at a wide range of switching frequencies. This feature is used here to design an embedded control objective to reach the desired switching frequency. The implementation of the cost function is done through modification of PCA-MPC measurements. These modifications allow one to obtain fast and precise estimates of the switching frequency, which, in turn, permits a fast control. The performance of this control strategy is evaluated through simulation and corroborated by experimental validation on a two-level three-phase, power converter. |
