Phase Current Measurement Diagnostic |
| 摘要 |
A method of controlling a motor of a power steering system is provided. The method generates a direct-axis voltage command and a quadrature-axis voltage command based on a current measurement signal received from the motor. The method transforms the direct-axis voltage command and the quadrature-axis voltage command into an alpha voltage command and a beta voltage command. The method determines an offset error in the phase current measurement based on the alpha and beta voltage commands. |

1. A method of controlling a motor of a power steering system, the method comprising:
generating a direct-axis voltage command and a quadrature-axis voltage command in a rotor reference frame based on a phase current measurement signal received from the motor; transforming the direct-axis voltage command and the quadrature-axis voltage command into an alpha voltage command and a beta voltage command in a stator reference frame; and determining an offset error in phase current measurement based on a voltage command in the stator reference frame. |
