Abstract

We demonstrate that linear, time varying, state feedback controllers, based on static passive output feedback, acting on exact open loop trajectory tracking error models of a large class of power electronics devices, semi-globally stabilize the trajectory tracking error to zero. The controllers are isomorphic to linear state feedback controllers, based on passivity and approximate linearization around the desired reference state trajectory. We present two design examples for rather different switched devices
