Fuzzy Logic vs. Classical PI Voltage Controller for a Self-Excited Induction Generator

摘要

Vector control algorithms are often used for control of the self-excited induction generators (SEIGs). This paper presents a comparative analysis of two different approaches for control of the SEIG's generated voltage in a vector control system. The classical approach based on the PI control is first considered and then a fuzzy-logic-based alternative is proposed. In particular, two different-type fuzzy logic (FL) controllers, Mamdani and Sugeno, are developed for the purpose. The analysis and comparison of the controllers' performance is provided for step changes in load and DC voltage reference. The obtained simulation results are experimentally verified.
