Abstract

A linear quadratic Gaussian with loop transfer recovery (LQG/LTR) controller is proposed for the efficient control of the output voltage of a buck-boost DC-DC power converter. The proposed control scheme guarantees excellent regulation of the output voltage. This is true even in the presence of large variations of the duty ratio and circuit parameters
