Abstract
The buck converter is essentially non-linear system. This property makes the controller difficult to be designed with the classical frequency-domain approach to ensure good output regulation and fast response over wide frequency bandwidth of input voltage and output load perturbations. Instead of this small-signal design technique, this paper presents fixed-frequency state trajectory control method that regulates the turn-on and the turn-off trajectory planes of the controlled switch to achieve optimum dynamic and static performances. The theoretical approach is verified by simulation of a 24 V/10 V (40 kHz) buck converter. © 2011 IEEE.
