A novel fuzzy logic controller for indirect vector control induction motor drive

This paper presents a novel fuzzy logic controller (FLC) for indirect vector control induction motor (IM) drive. The fuzzy logic speed controller is used in the speed loop. The 4 kW three-phase squirrel cage IM is fed by a current controlled voltage source inverter (CCVSI). The complete vector control scheme of the IM drive is implemented in real time using TMS320LF2812 digital signal processor. The simulation and experiments are carried out for the proposed drive system. The simulation model of the drive system is developed in MATLAB environment to analyze the performances of the novel IM drive system. The experimental results verify that the proposed FLC can not only enhance the robustness of the system, but also improve the steady-state precision and dynamic performances.
