Uses open-loop control (also known as scalar control or Volts/Hz control) to run a motor. This technique varies the stator voltage and frequency to control the rotor speed without using any feedback from the motor. You can use this technique to check the integrity of the hardware connections. A constant speed application of open-loop control uses a fixed-frequency motor power supply. An adjustable speed application of open-loop control needs a variable-frequency power supply to control the rotor speed. To ensure a constant stator magnetic flux, keep the supply voltage amplitude proportional to its frequency.

Calculates the offset between the rotor direct axis (d-axis) and position detected by the Hall sensor. The field-oriented control (FOC) algorithm needs this position offset to run the permanent magnet synchronous motor (PMSM) correctly. To compute the offset, the target model runs the motor in the open-loop condition. The model uses a constant (voltage along the stator's d-axis) and a zero (voltage along the stator's q-axis) to run the motor (at a low constant speed) by using a position or ramp generator. When the position or ramp value reaches zero, the corresponding rotor position is the offset value for the Hall sensors.

Calculates the offset between the d-axis of the rotor and encoder index pulse position as detected by the quadrature encoder sensor.

The controller needs this position to implement the field-oriented control (FOC) correctly in the rotor flux reference frame (d-q reference frame), and therefore, run the permanent magnet synchronous motor (PMSM) correctly.

Operates the resolver sensor to measure the rotor position. The resolver consists of two orthogonally placed stator windings placed around the resolver rotor winding. After you mount the resolver sensor over a PMSM, the resolver rotor winding rotates along with the shaft of the running motor. The controller provides a fixed frequency alternating excitation signal to the resolver rotor winding. When the resolver rotor rotates, the resolver stator windings produce output (secondary sine and cosine) signals that are modulated with the sine and cosine of the shaft angle or position. After receiving the secondary signals, the controller samples and normalizes them.

Determines the initial rotor position (in electrical radians) of a stationary interior PMSM. The example uses the pulsating high-frequency (PHF) method, which works when the motor has a high saliency ratio . The estimated rotor position ranges from 0 to 2π electrical radians. Due to a limitation in the PHF method, the estimated position may show ambiguity of π (pi). The dual-pulse (DP) method uses polarity detection to resolve the ambiguity of π and applies π compensation if there is an error.
