Abstract
An embodiment of a control system includes a pulse modulation module configured to generate a modulation signal controlling application of voltages to an electric motor, the modulation signal having a series of one or more successive pulses corresponding to a control cycle. The system also includes a current prediction module configured to receive a sampled electric current value from the electric motor taken at a sample time during a first control cycle n, predict a value of the electric current at a subsequent time related to an immediately following control cycle n+1 based on the sampled electric current value and a voltage applied to the motor during the first control cycle n, and output the predicted electric current value to the pulse modulation module. The system further includes a converter module configured to receive the modulation signal and output a voltage signal to the motor based on the modulation signal.
