Model Reference Adaptive Control for Split DC-Link Based Dual Active Bridge Converter

This paper develops a Model Reference Adaptive Controller (MRAC) scheme for a split de-link dual-active-bridge (SDLDAB)-based multiport converter (MPC). The proposed controller's control parameters are adaptively adjusted as the converter parameters vary under different conditions. It does not require the state-space modelling of the converter, unlike in a conventional proportional-integral (PI) controller. By estimating the control parameters using an adaptation law, the performance of the MRAC is compared with a PI controller in order to illustrate the effectiveness and resilience of the adaptive operation. The developed method was tested on MATLAB/Simulink software.
