Control Of Electric Machine Drive System Apr 2026

Faster torque response than FOC; no coordinate transforms.

Directly switches inverter states based on torque errors.

The actuator (PMSM, Induction, or DC) converting energy. ⚙️ Key Control Strategies Scalar Control (V/Hz) Control of electric machine drive system

Converts DC or AC into the required motor input.

Higher torque ripple and variable switching frequency. ⚡ Essential Features Faster torque response than FOC; no coordinate transforms

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.

Runs algorithms (like PID or FOC) on a DSP or FPGA. Faster torque response than FOC

Small fluctuations in torque that cause vibration.
