Two predictive schemes based on a linear extrapolation technique are developed to compensate the sampling time delay present in digital control, thus increasing the bandwidth of the control loop. Characterized by a low computational effort, these schemes are perfectly suited for fast systems such as high-performance DC switchmode power supplies. Results with and without the proposed prediction schemes are provided for comparison
