Runs algorithms (like PID or FOC) on a DSP or FPGA.
Maintains a constant ratio between voltage and frequency. Pros: Simple to implement; no position sensor needed. Cons: Poor dynamic performance; low torque at low speeds. Vector Control (Field Oriented Control - FOC) Mechanism: Decouples flux and torque-producing currents. Control of electric machine drive system
Operates the motor above rated speed by reducing flux. Runs algorithms (like PID or FOC) on a DSP or FPGA
Faster torque response than FOC; no coordinate transforms. Control of electric machine drive system
Controls an AC motor like a separately excited DC motor. Pros: High efficiency; excellent dynamic response. Direct Torque Control (DTC)
