摘要:
A method of starting a permanent magnet synchronous motor (PMSM) with field oriented control (FOC) includes: opening a first control loop of the PMSM; setting a first direction for a first current component of the PMSM; aligning a rotor of the PMSM to the first direction; after aligning the rotor, setting a second direction for the first current component, where the second direction is rotated from the first direction by 90 degrees; after setting the second direction, starting the rotor while the first control loop of the PMSM remains open; after starting the rotor, increasing a rotation speed of the rotor by operating the first control loop in a first closed-loop mode; and after increasing the rotation speed of the rotor, controlling the rotation speed of the rotor by operating the first control loop in a second closed-loop mode different from the first closed-loop mode.
