Abstract:
A controller includes a sampling module that samples a signal indicative of the output voltage, a filter module that filters out a ripple component of a sampled signal to generate a filtered signal, and a proportional-integral-derivative (PAID) controller that generates a duty cycle control signal. The PAID controller includes a first component that scales sample values of the filtered signal to generate a first component signal, a down-sampling module that generates a down-sampled signal, and a storage module that stores a value of the down-sampled signal. The PAID controller also includes a second component that generates a second component signal as a product of a factor and a difference signal between each sample value in the filtered signal and stored value, a third component that scales and accumulates the down-sampled signal to generate a third component signal, and a summing module that sums the first, second and third component signals.

Claim (Index 34):
The controller as recited in  claim 31 , wherein:\n the filter module, comprises:\n a ripple component estimation module arranged to estimate the ripple component by calculating, for each sample of a plurality of the sampled signals separated by an integer number of periods of the oscillatory reference signal, an average sample value using the sampled signal and sample values obtained at corresponding points in preceding periods of the oscillatory reference signal; \n a moving average calculation module arranged to calculate a moving average of the sampled signal by calculating, for each sample of the plurality of the sampled signals, an average of a predetermined number of preceding sample values; and \n a subtraction module arranged to generate the filtered signal by calculating a difference between an estimated ripple component and a sum of the sampled signal and a calculated moving average; and \n the second component is arranged to delay the stored value of the down-sampled signal until a period following the oscillatory reference signal to generate the second component signal.
