Abstract
In an example, a device for operating a switching converter is configured to determine a set of perturbed duty cycle values for a converter. A perturbation sequence is superimposed simultaneously onto a duty cycle value for each phase of the converter to form the set of perturbed duty cycle values. The device is further configured to determine an output voltage of the converter that occurs when the converter operates based on the set of perturbed duty cycle values, determine a coefficient vector of system parameters for the converter based on the output voltage and the set of perturbed duty cycle values, and tune a controller based on the coefficient vector. The duty cycle value for each phase of the converter is based on a respective command duty cycle value of a set of command duty cycle values output by the controller.
