EXTERNAL DISTURBANCE DETECTION SYSTEM AND METHOD FOR TWO-PHASE MOTOR CONTROL SYSTEMS |
摘要 |
A system includes a power control module, a period determination module, and a control module. The power control module controls current through stator coils of a motor to rotate a rotor. The period determination module determines a first length of time between a first set of induced stator coil voltages and determines a second length of time between a second set of induced stator coil voltages. The control module determines whether an external disturbance disturbs rotation of the rotor based on a difference between the first and second lengths of time. |
