Comparative study of Pi and model predictive control of the dual active bridge DC-DC converter

The use of renewable sources requires suitable power electronics for integrating energy into the network. For this purpose, bidirectional converters become essential elements. Over the past years, a particular topology of bidirectional converter has attracted the attention of researchers due to its benefits: "The Dual Active Bridge converter". The operation and control of this topology must be thoroughly studied to increase its performance. In this thesis, a comparative evaluation of PI Control and Model Predictive Control of the DAB converter for use in a unidirectional power transfer application was conducted to choose the best control approach for the system operation. The methodology chosen for this analysis was the investigation of the system operation in three (3) different working scenarios: the steady-state, the dynamic response, and the input voltage change (disturbance). The predictive voltage control approach was developed as an S-Function for simulation in MATLAB.
