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 38):
A method for generating a duty cycle control signal for regulating an output voltage of a switched mode power supply, comprising:\n sampling a signal indicative of the output voltage at a frequency higher than a frequency of a oscillatory reference signal to produce a sampled signal; filtering out a ripple component from the sampled signal to generate a filtered signal; and generating the duty cycle control signal based on the filtered signal, comprising:\n scaling sample values of the filtered signal by a first scaling factor to generate a first component signal; \n sampling a signal based on the sampled signal at the frequency of the oscillatory reference signal to generate a down-sampled signal; \n storing a value of the down-sampled signal; \n calculating values of a product of a second scaling factor and a difference signal between each sample value of the filtered signal and a stored value of the down-sampled signal to generate a second component signal; \n scaling the down-sampled signal by a third scaling factor and accumulating values of a scaled, down-sampled signal to generate a third component signal; and \n generating the duty cycle control signal as a function of the first, second and third component signals.
