Comparative Analysis of Two Torque Control Strategies for 6/4 Switched Reluctance Machine

摘要

This work developed two direct torque control strategies to the switched reluctance machine. The direct torque control based on space vector control and direct instantaneous torque control. The studio is performed using the asymmetric bridge converter that drives the three-phase motor of six poles in the stator and four poles on the rotor. At the beginning shows the principles of operation of the switched reluctance machine for developing electromagnetic torque, the mathematical principles and the keys of switching strategies for controlling in the space vector, as well as the operating principles of the direct instantaneous torque control, at the end is compared, the results of both direct torque control strategies. The simulations were performed in the software SimPowerSystems? of Matlab/Simulink?.
