Fuzzy pbkp_redictive DTC of induction machines with reduced torque ripple and high-performance operation

Abstract:

This paper proposes an enhanced strategy for direct torque control (DTC) combining artificial intelligent (AI) and pbkp_redictive algorithms. The advantages of this merge are in the solution of closed-loop controlled induction machine (IM) problems. Pbkp_redictive DTC (P-DTC) methods reduce the high torque ripple and improve the performance at both starting condition and low mechanical speed operation. However, P-DTC depends on the IM parameter's knowledge. The approach here is the introduction of fuzzy logic control with dynamic rules based on the P-DTC law's to reduce the parameter dependency and improve the performance of P-DPC. Additional comparative performance study of eight modulation strategies under the proposed fuzzy-pbkp_redictive DTC (FP-DTC) is conducted. It results that the space-vector modulation (SVM) is the most suitable scheme with the best combination of criteria such stator current total …
