Four sensorless control schemes for the operation of induction motors in the field-weakening region are compared and assessed in terms of performance and complexity. These four control schemes fully utilize the maximum available voltage and current and can produce the maximum possible torque in the entire field-weakening region. For comparison, the four control schemes are implemented on the same experimental platform, i.e., the same DSP board, power inverter, and motor drive. In this way, it is possible to assess not only the performance of each solution, but also its requirements in terms of computational time, tuning complexity, parameter knowledge, and stability of operation.

Abstract
Four sensorless control schemes for the operation of induction motors in the field-weakening region are compared and assessed in terms of performance and complexity. These four control schemes fully utilize the maximum available voltage and current and can produce the maximum possible torque in the entire field-weakening region. For comparison, the four control schemes are implemented on the same experimental platform, i.e., the same DSP board, power inverter, and motor drive. In this way, it is possible to assess not only the performance of each solution, but also its requirements in terms of computational time, tuning complexity, parameter knowledge, and stability of operation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
