Abstract
In high-performance servo applications a rapid and direct torque control (DTC) is desired. However, the conventional direct torque control based on the 60 degrees region used the position signal to select the proper space voltage vector, results in large torque and flux linkage ripple. In order to solve this problem, a novel DTC scheme for the permanent magnet synchronous motor (PMSM) is proposed, which based on voltage space vector and stator flux linkage sectors subdivision. In this scheme, the traditional six voltage vectors and six flux sectors are subdivided into 12 voltage vectors and 12 flux sectors method to find the optimal voltage vectors. The simulation results show that the presented method is superior to the conventional DTC, and DTC based on sectors subdivision can decrease the torque ripple drastically and enhance the control performance.
