Pso Based Fuzzy Logi̇c Control Desi̇gn for a Dc/Dc Boost Converter

Abstract

In this study, a DC / DC boost converter was designed for wind energy systems in Matlab / Simulink and output voltage control was examined under variable load conditions. The designed converter was controlled to obtain desired constant output voltage when the input voltage was variable or to obtain desired variable output voltage when the input voltage was constant. The system performance is compared using classical PI controller and Fuzzy Logic Control (FLC). Also, some system parameters are optimized with PSO to improve system performance using the weighted absolute error (ITAE) criteria as a fitness function. Thus smarter and more efficient control is provided for the proposed system. The simulation study is realized via Matlab/Simulink and the results are evaluated.

Ga-Based Fuzzy Logic Controller With Booster Type Dc-Dc Converter

“…In this case, the circuit is not operated being unloaded; otherwise the output voltage increases excessively and causes damage to the circuit. This event happening within Td<t≤T time interval is shown in Figure 3 [8]. As it would be seen from Figure 3, within the t on time interval, e.i.…”

Implementation of Particle Swarm Optimization in Fuzzy Logic Controller for an Improved Transient Response of a DC/DC Buckboost Converter

“…Sundareswaran et al [3] used a buck-boost controller to regulate the voltage output and used PSO in the feedback controller but did not employ FLC as the control paradigm. While looking at the work of Ömür Akyazı [5], he showed how he used PSO as a tuning parameter in a fuzzy logic control scheme for a dc/dc boost converter, but not a buck converter. FLC was employed on several types of converters in the work of S.Maity et al [6], but no optimization of FLC was done.…”
