Direct Torque Control of Switched Reluctance Motors
Switched reluctance motors (SRM) have gained more popularity in recent years because of their simple structure, low cost, high reliability, and high torque-to-mass ratio. However, the applications of the SRM have been limited because of their large torque ripple, which causes noise and vibration problems. In order to solve these problems，a novel direct torque control (DTC) methodology is directly used to control torque of the SR motor through the control of directly used to control torque of the SRM through the control of the magnitude of the flux linkage and the change in speed (acceleration or deceleration) of the stator flux vector. It can be seen from the simulation results that this scheme has well regulated the torque output of the motor within hysterisis band. Furthermore, the scheme is very simple and can be implemented with low cost microprocessor hardware.
