The Application of Fuzzy Direct Torque Control for Permanent Magnet Synchronous Motors
In order to resolve the problem of big torque ripple in direct torque control of permanent magnetic synchronous motor (PMSM DTC),a PMSM DTC method based on fuzzy control is proposed.The hysteresis controllers in conventionaI PMSM DTC were replaced by a fuzzy controller.The torque error,stator flux linkage error and the stator flux vector anglllar position are all properly fuzzificated into several fuzzy subsets.so that a more suitable space voltage vector can be selected to minimize the torque and flux linkage ripples.The simulation results show that both the dynamic and steady state performances of PMSM areimproved based on this fuzzy DTC.
