Abstract
An algorithm for design of synergetic control is derived, using as an example a system containing buck choppers with constant power load J.G. Ciezki et al. (1998). The closed loop system behavior is compared to that of the same system controlled by feedback linearization control. As a result, it is shown that synergetic control has better dynamics and a faster response. This system nullifies steady state error not only of output voltage but also in current sharing among parallel converters.
