Controle preditivo aplicado a um conversor CA-CC monofásico multiportas
| Resumo: | The purpose of this work is to implement the control of a single-phase, multi-port AC-DC converter with high frequency isolation based on the DAB converter and associated with the Three-State Switching Cell (3SSC) applied to a distributed generation system. The converter has four ports, one with alternating current and three ports with direct current, one connected to photovoltaic panels, another connected to a battery bank and the last one with the possibility of being connected to a load. A model-based predictive controller (MPC) named GPC is adopted to control the DC-link voltages and traditional integrative proportional controllers with filter are used in the current loops of the AC input and the bank of batteries. The GPC controller used is of type MIMO to deal with the coupling between the control variables. The validation of the proposed control strategy was done through simulations with the PSIM software. In addition, experimental tests were carried out confirming the functioning of the solution in addition to comparing it with a traditional control strategy |
