Abstract
A digital signal processor (DSP) is operable to receive a single-phase back electromotive force signal (back-EMF) fed back from a motor and control an inverter for driving the motor based on the single-phase back-EMF signal. The DSP includes an electrical angle building module, a rotation speed control module, and a pulse width modulation control module. In addition, the DSP further includes a field-weakening compensation module. The field-weakening compensation module is operable to automatically regulate an electrical angle based on a rotation speed of the motor and a set of predetermined compensation parameters so that the DSP can be operable to achieve an adaptive control. Furthermore, a motor control system and method are disclosed herein.
