Abstract:

The present study proposes an interval type-2 Takagi-Sugeno-Kang (TSK) fuzzy controller for voltage mode control of an elementary series Luo converter with negative output voltage and operating at continuous conduction mode. Under different controlling scenarios, the proposed controller aims to improve dynamic response of elementary series Lou converter with negative voltage output. To this end, the circuit model of elementary series Lou converter with negative voltage output was analyzed, and circuit element boundary values were calculated for continuous conduction mode. The dynamic performance of the proposed controlling structure was later analyzed using type-1 TSK fuzzy controller against various disturbances such as changing reference and input voltage and load in Matlab/Simulink environment. When the comparative control performance values obtained from the simulation study are examined, it was observed that the proposed controller has better improvement values compared to the type-1 TSK fuzzy controller in terms of settling times for all control situations.
