Method and apparatus for torque ripple compensation |
摘要 |
Torque ripple in brushless DC motors is reduced by compensation of signals controlling energization of motor stator windings. Motor current magnitude is compensated in response to compensation factor values correlated to the ratio of actual torque to ideal torque at constant current at various relative positions of a motor rotor and stator. A motor current command component associated with a commanded torque is compensated for cogging torque associated with motor magnetization. Measured relative position values are compensated to account for torque profile distortions associated with motor current magnitude.
