Ripple correlation control, with some applications

Ripple correlation control is a nonlinear control approach applicable to power electronic circuits. It makes use of voltage, current, or power ripple and correlates this with switching functions to effect control. The technique is especially well suited to power electronics because ripple is inherent, and can be treated as an internal perturbation. Ripple correlation control directly supports cost-function minimization and maximization. It can be applied, for example, to dynamic power optimization. It has been applied to adaptive dead time adjustment, solar power processing, and motor power minimization. Potential future applications include active maximization of converter efficiency and other nonlinear functions.
