Abstract
A method for operating a vapor compression system modifies each control signal of a set of control signals with a corresponding modification signal of a set of modification signals, wherein each modification signal includes a perturbation signal, and the pertubation signals haver different frequencies and determines a metric signal representing perturbations in the system caused by the set of modification signals. Next, the method adjusts a value of each modification signal based on a function of a phase between the modification signal and a corresponding frequency component of the metric signal.
