3.3. Principle of control algorithms

  • Proper operation of the whole system is strongly dependent on the position/speed sensor.
  • Special attention is paid to sensorless methods, but they still suffer by poor performance at very low speeds.
  • Sensorless techniques are used for fault diagnostic (sensor data validation).
  • The control algorithm has crucial impact on drive performance and effectivity – it makes the drive unique.
