Abstract
A DC-DC converter is widely used in various applications for energy conversion systems. This paper focuses on a home energy management system that uses boost and buck converters connected to the same DC link voltage, treating the system as a multi-input multi-output (MIMO) system. A state-space averaging model analysis is used to model the system. The proposed dynamic current decoupling control compensates the DC link voltage at each input. The proposed approach calculates that the elements of the off-diagonal terms become zero. The diagonal terms are first-order systems. The model analysis suggests that the compensation of the duty error needs to be stable in the DC link voltage. The experimental test bench system is constructed and tested to verify the proposed control. By system identification, the model represents the major dynamics of the actual system. Nyquist stability analysis for the MIMO system depicts that the conventional control might be unstable due to MIMO interaction. Step responses also verify that the proposed control suppresses the overshoot voltage and converges faster compared to conventional voltage control.
