Virtual Electrical Machinery Laboratory: A Fuzzy Logic Controller for Induction Motor Drives

摘要

In this paper, an educational tool was presented to supplement existing undergraduate and graduate electrical machinery laboratory instruction, so that students could establish a thorough understanding of a fuzzy logic controller (FLC) and an indirect vector control induction motor (IM) drive using the FLC. The tool describes the basic operation of the indirect vector controlled IM drive and, application of fuzzy logic speed control to the vector controlled IM. The FLC was applied to the speed loop, replacing the conventional PI controllers. The educational tool allowed the student to interact with the indirect vector controlled IM drive using the FLC and to examine its responses on a dynamic and instantaneous basis under different operating conditions.
