Direct Torque Control for Switched Reluctance Motors

Traditional voltage vector selection methods primarily consist of two approaches: vector control and direct torque control. In previous applications, vector control has been predominantly used for switched reluctance motor regulation. However, direct torque control proves more advantageous in specific scenarios. Essentially, direct torque control achieves torque regulation by modulating the motor's current vector. This method significantly enhances motor response speed and control precision by reducing uncertainties in the control process. From an implementation perspective, direct torque control algorithms typically involve real-time torque calculation, flux linkage estimation, and optimal voltage vector selection through hysteresis comparators or lookup tables. The control logic can be implemented using embedded C code or Simulink models with Park/Clarke transformations for coordinate frame handling. In summary, direct torque control serves as a highly practical methodology applicable to switched reluctance motor drives, delivering superior performance through simplified control architecture and improved dynamic response.
