FOC face DTC and scalar control topologies [21].
| Feature | FOC | Scalar control (V/f) | DTC |
|---|---|---|---|
| Torque control | Precise | Indirect | Good but with ripple |
| Speed control | Accurate | Poor at low speed | Moderate |
| Dynamic response | Fast | Slow | Very fast |
| Efficiency | High | Moderate | High |
| Torque ripple | Low | N/A | High |
| Implementation complexity | High | Low | Moderate |
| Sensorless control feasibility | Yes | No | Yes |
