Control Of Electric Machine Drive System Instant

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.

Converts DC or AC into the required motor input. Control of electric machine drive system

Monitors current, voltage, and rotor position/speed. Maintains a constant ratio between voltage and frequency

Allows motoring and braking in both directions. Control of electric machine drive system

Small fluctuations in torque that cause vibration.
