Field-Oriented Control of Induction Motors with Simulink, Part 1: What Is Field-Oriented Control?

Learn how field-oriented control provides high-performance torque or speed control for various motor types, including induction motor, permanent magnet synchronous machines (PMSMs), and brushless DC (BLDC) motors.

The video introduces a typical field-oriented controller architecture and explains various components involved. Those include AC motor, power inverter, Clarke, Park, and inverse Park transforms, inner-loop current controller, optional outer-loop speed or flux controller, space vector modulator algorithm, and an optional rotor speed and position observer.

The video explains how Park and Clarke transforms are used to simplify computations by converting AC current and voltage waveform into DC signals.  Continuous and discontinuous modulation schemes for space vector modulation are discussed.
