Simulation Diagram of Direct Torque Control for Permanent Magnet Synchronous Motor

Here, I would like to share a simulation diagram of direct torque control (DTC) for a permanent magnet synchronous motor (PMSM). The diagram demonstrates the motor's operational status and the variations of related parameters, helping us better understand and master the working principle of the motor. Through this diagram, we can observe the motor's operating conditions under different loads, as well as its performance characteristics under various conditions such as voltage and current fluctuations. This proves highly beneficial for motor design, debugging, and optimization. From a code implementation perspective, the simulation likely utilizes mathematical models representing PMSM dynamics, torque and flux estimators, and hysteresis comparators for direct torque control. Key functions would include Clarke/Park transformations for coordinate conversion, stator flux linkage calculation, and torque estimation algorithms. The implementation typically involves discretizing the control algorithm with appropriate sampling times and incorporating voltage vector selection tables based on flux and torque error status. I hope everyone can share their experiences and insights to facilitate mutual learning and progress in motor control technologies.
