“…In these converters, different control loops are usually designed for each output variable to deal with the different modes of operation and the cross-coupling between the control loops [2]. The k factor methodology proposed in [7] was used to tune the independent controllers in [8], [9], and [10]. Although this strategy provides satisfactory results, the simultaneous operation of the controllers causes interference between the loops, leading to unpredictable behavior during the design.…”

This work aims to implement the control system of a single-phase, multi-port AC-DC converter with high-frequency isolation based on the dual active bridge (DAB) topology associated with the three-state switching cell (3SSC) applied to a distributed generation system. The converter has one ac port and two dc ports, this being a multi-input, multi-output (MIMO) system in which there is a coupling between the input and output variables. The generalized predictive control (GPC) is chosen to regulate the dc-link voltages. GPC is a well-consolidated approach in the literature, which can deal with MIMO coupled systems while presenting friendly-tuning rules. The current loop employs a traditional proportional plus resonant (P+R) controller because it has a single-input, single output (SISO) characteristic, as advanced controllers are unnecessary. Experiments are performed on a 1-kW prototype to validate the performance of the developed controller and show its advantages compared with traditional control strategies.INDEX TERMS Dual active bridge converter, generalized predictive control, model predictive control, multi-port converters, predictive control.
