Robust Fuzzy Logic Current and Speed Controllers for Field-Oriented Induction Motor Drive

다국어 초록 (Multilingual Abstract)

This paper presents analysis, design and simulation for the indirect field orientation control (IFOC) of induction machine drive system. The dynamic performance of the IFOC under nominal and detuned parameters of the induction machine is established. A conventional proportional plus integral-derivative (PI-D) two-degree-of-freedom controller (2DOFC) is designed and analysed for an ideal IFOC induction machine drive at nominal parameters With the desired dynamic response Varying the induction machine parameters causes a degredation in the dynamic response for disturbance rejection and tracking performance with PI-D 2DOF speed controller. Therefore, conventional controllers can not meet a wide range of speed tracking performance under parameter variations. To achieve high - dynamic performance, a proposed robust fuzzy logic controllers (RFLC) for d-axis rotor flux, d-q axis stator currents and rotor speed have been designed and analysed These controllers provide robust tracking and disturbance rejection performance when detuning occures and improve the dynamic behavior. The proposed RFL controllers provide a fast and accurate dynamic response m tracking and disturbance rejection characteristics under parameter variations. Computer simulation results demonstrate the effectiveness of the proposed RFL controllers and a robust performance is obtained for IFOC induction machine drive system.
