Development of a Fuzzy Logic Based Control Algorithm for Charge-Discharge of a Battery System

Abstract

In this study, a fuzzy logic controller–based battery charge-discharge control algorithm has been developed to obtain power from a simulation model of an energy system continuously and stably. The current and voltage of the DC busbar, as well as the battery unit, are continuously monitored and used as input data for the algorithm's fuzzy logic controller. And the output of the fuzzy logic controller used as duty ratio for the DC-DC buck boost converter’s switching elements. Thus, charge-discharge control of a battery unit to be used as an energy storage unit in an energy system is provided with a developed fuzzy logic-based controller. Also, with the developed simulation model, suitable codes for the TMS320F28335 Digital Signal Processor (DSP) were produced with the embedded code generation method to be used in real world applications.
