Abstract

In this study,
a booster–type DC-DC converter is designed by Matlab/Simulink Environment and an
output voltage control has been analyzed for different load conditions. The
designed DC-DC converter is controlled for different scenarios such as variable
input-constant output voltage and constant input-variable output voltage
references. The converter controller performance is observed with using
classical Proportional+Integral (PI) controller and Fuzzy Logic Controller
(FLC). On the other hand, the controller parameters are determined by employing
Genetic Algorithm (GA) according to Integral of the Time weighted Absolute Error
(ITAE) to improve the controller performance. Thus, more efficient and
intelligent controllers are obtained for the DC-DC converter system. The system
simulation is realized by the Matlab/Simulink and results are compared with
each other.
