Abstract
A robust starting system and method for an interior permanent magnet synchronous motor, suitable for commercial fan and blower drive applications. A comprehensive starting control process is provided that utilizes control flags to implement closed-loop control accounting for any pre-existing rotor movement, controlling the motor speed from an initial speed to a destination speed. A universal dqController provides selective configurability for collecting information regarding the initial state of the motor, as well as starting and operational motor control. Dynamic high frequency injection enables the use of HFI outside the normal standstill motor speeds by intelligently decoupling the high frequency and rotor movement portions of the stator current response.
