Abstract

A performance comparison of four control techniques (PID, LQR, SDRE and ANLPID-GGF) applied to a Buck converter is presented. The controllers are set so the operating point of the closed loop system presents the same natural frequency. The poles placement technique was used. Analyses of the results are performed.
