Simulink-HDL cosimulation of direct torque control of a PM synchronous machine based FPGA

This paper presents the cosimulation of Direct Torque Control (DTC) for a Permanent Magnet Synchronous Machine (PMSM) based on the technology of Field Programmable Gate Array (FPGA). This approach is suitable to visualize the behavior of the control system before its implementation, which can prevent problems that could lead to damage in the machine under control. The DTC algorithm and the methodology for hardware description language in VHDL are presented. The cosimulation is carried out based on Matlab/Simulink and Active-HDL; simulation results are presented to validate the effectiveness of the presented methodology.
