Direct Torque Control of a Permanent Magnet Synchronous Motor

This example demonstrates the implementation and experimental validation of a Direct Torque Control (DTC) strategy for a Permanent Magnet Synchronous Motor (PMSM). The control algorithm directly regulates motor torque and stator flux using measured currents and rotor position, enabling fast dynamic response with a simple control structure. The implementation includes torque and flux estimation, speed control, field weakening, and inverter switching state generation. The example is developed using imperix control hardware and software tools, with experimental results highlighting the achievable torque and flux control performance, ripple behavior, and speed tracking capabilities.
