Abstract

DC-DC converters are electronics elements which change voltage level based on switching. Unlike linear circuit topologies,modeling and controlling of DC-DC converter circuits are very difficult because of their switched structure. Conventional controllers such as PI, PD and PID are insufficient to control non-linear systems. These controllers cannot give good performance under transient and steady state conditions. Intelligent controllers based on fuzzy logic are required in order to improve the performance of non-linear systems. Fuzzy logic control methods are used to solve many engineering problems. Interval Type-2 Takagi-Sugeno-Kang Fuzzy Logic controller (IT2TSKFLC) is more robust to overcome uncertainties and nonlinearities compared to Type-1 Fuzzy Logic controller (T1FLC). In the present study, an IT2TSKFLC is proposed for the robust control of boost converter. The dynamic performance of proposed controller was analyzed under disturbances such as input voltage change and output load change using MATLAB/Simulink.
