An Experimental Assessment of Predictive Current Control Strategies for Three-Phase Inverter

This paper presents an empirical investigation of two current control methods for two-level inverter-fed RL loads: the conventional Finite-Control-Set Predictive Current Control (FCS-PCC) and a simplified FCS-PCC. The simplified PCC is considered to minimize the computational workload of the conventional PCC without sacrificing its control performance. However, the simplifying mechanism of the simplified PCC is dependent on the load parameters. Hence, an experimental analysis of the controller is required in terms of steady-state current tracking and current total harmonic distortion (THD) under load parameters variation. Experimental results show that both algorithms of PCC are load parameters dependent. Nevertheless, the simplified PCC is more sensitive to the load parameters variation than the conventional PCC.
