ABSTRACT:
Complex filters may be used to achieve compensation of a plant, corresponding for example to a power regulator or point-of-load (POL) regulator. Digital filter coefficients may be mapped to analogous poles and zeros, or they may be mapped to values of the quality factor (Q) of the output, frequency, and gain. The plant may be observed and characterized using a network analyzer to generate the Bode plot (or Nyquist plot) for the plant. The digital filter coefficients may be mapped to features that may be identified on the Bode plot (or Nyquist plot) to easily correlate characteristics of the digital filter or digital compensator to the plant characteristics. The mapped features may be adjusted, for example by a user, either manually or by executing one or more optimization algorithms, to achieve the desired results relative to the Bode plot (or Nyquist plot). The mapped features may then be reverse mapped to the digital filter or digital compensator coefficients to fine tune and implement the digital filter or digital compensator.
