An Interval Type-2 Fuzzy Based DTC of IMD Using Hybrid Duty Ratio Control
2020
This article provides an interval type-2 fuzzy-based direct torque control (IT2FDTC) of the induction motor (IM) drive, (IMD) in which a hybrid duty ratio control (HDRC) technique is used to activate a two-level inverter. Moreover, it is implemented with the help of DSPACE-1104 controller in a real-time application using a 2HP IM and compared its overall performance with a conventional proportional-integral direct torque control (CPIDTC) using space vector modulation (SVM) technique. The IT2FDTC can be provided less torque and flux ripples with a faster dynamic performance of IMD over a CPIDTC. This due to the fact that a three-dimensional Mamdani type-2 fuzzy controller along with the centroid method is used in the defuzzification process, for the proposed control method. The proposed method of study effectively controls the gains of PI and HDRC. Also, HDRC has a total of five possible duty ratios in which two novel duty ratios are introduced including two clamping and one SVM duty ratios to further improve the current/flux/torque harmonic profile performance of IMD than CPIDTC.
