Title: Online Stator Reference Flux Approach to Torque Ripple Minimization for SPM Drive using Fuzzy and PI Controllers
Authors: N. Krishna Kumari and G. Tulasi Ram Das and M.P.Soni
Abstract: In this paper different DTC space vectors with online stator flux reference for surface mounted permanent magnet synchronous motor (SPM) drive is carried out using fuzzy and PI speed regulators. The stator reference flux is calculated offline by using the machine parameters conventionally. In the proposed method “A Maximum Torque per Ampere (MTPA)” principle is applied, wherein the online stator reference flux is calculated from torque reference, direct stator flux and quadrature stator flux instead of stator flux linkage. Three sets of DTC space vectors are considered with MTPA operation for analysis purpose and the performance of the three control schemes are evaluated in terms of torque ripple, flux ripple and transient response to step variations in torque and speed control commands. Simulation results using MATLAB/SIMULINK show the effectiveness of the proposed method.
