H∞ LPV Control with Pole Placement Constraints for Synchronous Buck Converters with Piecewise-Constant Loads

This paper addresses the output regulation problem of synchronous buck converters with piecewise-constant load fluctuations via linear parameter varying (LPV) control scheme. To this end, an output-error state-space model is first derived in the form of LPV systems so that it can involve a mismatch...
