Modeling and Simulation of Direct Torque Controlled PMSM for PHEV

摘要

Direct torque control (DTC) method for permanent magnet synchronous motor (PMSM) used as Integrated Starter/Generator (ISG) in PHEV was analyzed. The DTC PMSM model, with PI produced a voltage space vector based on torque PI regulator and flux linkage PI regulator, was built up based on Matlab/Simulink and all simulation blocks were discussed. The results showed that this scheme was simple and effective, also had a good robustness. It is easy to realize in PHEV application, while to keep the fast torque response and little flux linkage and torque fluctuation.
