METHOD FOR CONTROLLING SWITCHING POWER CONVERTER USING PERIODIC INVARIANCE SET

摘要

A method for controlling switching power converter using periodic invariance set is provided to be applied to a high accuracy industrial servo system and submicron and nano-scale precision servo system by using a constant region of the predictive control field. A method for controlling switching power converter is comprised of steps: modeling a switching power converter by a plurality of other dynamic models according to the on/OFF state of the power switch of the switching power converter(S100); making the conversion sequence of the power switch in order to apply the other feedback-control corresponding to the dynamic model and defines the periodic constant region through the change of the limited dynamic model of the times(S200); controlling the switching power converter through the application of the conversion sequence(S300); allowing the use of the several state feedback-controls and the periodic constant region allows state value provisionally to go out the constant region(S400).
