Control Of Electric Machine Drive System Today

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.

Small fluctuations in torque that cause vibration. Control of electric machine drive system
