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...
The paper deals with controlled PM-brushless drives in configuration ldquosingle-inverter, dual-motorrdquo operating with unbalanced loads at the shafts of the two motors. Some control techniques are analyzed and their relevant features are compared. Starting from some simple control circuits which refer to an equivalent ldquosingle-inverter, single-motorrdquo configuration, some compensation blocks...
The paper deals with controlled PM-brushless drives in configuration "ingle-inverter, dual-motor" operating with unbalanced loads at the shafts of the two motors. Predictive control technique is analyzed and two control circuits are compared. Starting from some simple control circuits which refer to an equivalent "single-inverter, single-motor" configuration, some modified blocks...
