Comparação de Estratégias de Controle Preditivo do tipo Finite-Control-Set: Tradicional de Corrente e abordagems Robustas do tipo Deadbeat e DTIA para Motores de Indução

Abstract

Climate change and increasing electrification driven by renewable energy are driving research into system electrification, driving interest in electric drive technologies. Among the motors used in modern drives, three-phase induction motors stand out for their low cost, robustness and technological modernity. This article explores three predictive control methods: Current Type Finite-Control-Set (PCC), Robust Deadbeat (RPCC-Deadbeat), and Robust Using discrete time integral action (RPCC-DTIA). These parameters are promising for their fast and flexible dynamic response with nonlinearities. Simulation results performed in Simulink compare the performance of PCC, RPCC-deadbeat and RPCC-DTIA. The analyzes demonstrate the differences between the strategies through dynamic responses, in regime and THD, in addition to evaluating the behavior of the controllers in the face of variations in machine configurations, such as resistance and inductance. The computational cost is also measured to complement the analyses.
