Control Of Electric Machine Drive System May 2026

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.

Controls an AC motor like a separately excited DC motor. Pros: High efficiency; excellent dynamic response. Direct Torque Control (DTC) Control of electric machine drive system

Converts DC or AC into the required motor input. Maintains a constant ratio between voltage and frequency

Monitors current, voltage, and rotor position/speed. Control of electric machine drive system

Minimizing copper and switching losses during operation.

Runs algorithms (like PID or FOC) on a DSP or FPGA.

Feeds energy back to the source during deceleration.
