Abstract
A system for speed regulation of an induction motor including an induction motor configured to be driven by a 3-phase alternating voltage (AC) signal. The system further includes an encoder configured to measure a shaft speed of the induction motor. Further, the system includes a variable frequency drive (VFD) device configured to generate the 3-phase AC signal to drive the induction motor. The system also includes a controller configured to generate a control voltage signal based on the measured shaft speed of the induction motor and a reference speed, the control voltage signal being input to the VFD device to control a frequency of the 3-phase AC signal.
