Polynomial control strategy of the DC/DC converter for energy share between Supercapacitors and battery

Résumé

This paper deals the embedded energy share between Supercapacitors (SC) and batteries. SC modules are dimensioned for peak power requirement and batteries provide the power in steady state. This last is directly connected to the DC-bus to maintain the voltage level between 38V and 60V. A buck-boost converter is interfaced between the SC and the DC-bus to manage the available energy. The originality of this study is focused on energy management strategy between SC and batteries. The proposed strategy is based on polynomial (RST) controller. Due to cost and available components (no optimized) such as batteries and semiconductors, the experimental test bench is designed in reduced scale. The used packs of SC include two modules of 10 cells in series for each one, and present a maximum voltage of 27V. The buck-boost converters control algorithms are implemented in PIC18F4431 microcontroller. Experimental and simulation results obtained from polynomial control strategy are presented, analyzed, and compared to proportional integral ones.
