Generalized Stability Control for Open-Loop Operation of Motor Drives

This paper proposes a general approach to designing a stability control for open-loop operation that can be used for either induction motor, permanent magnet synchronous motor, or any other motor drives. A speed or frequency set point is adjusted by a frequency compensation value to provide the stability control to mitigate hunting or motor stoppage. The proposed method can be utilized in either conventional motor drives or motor drives with an output filter and a transformer used for oil pump applications.
