Abstract :
In this paper, the digital controller design has been considered for output voltage compensation of DC-DC Buck Converter in Z-domain. The essential idea is to pattern from the samples of high-order ideal controller and use Integral of Squared Error (ISE) in order to determine the digital PID coefficients. This approach presents the significant contribution in accuracy increase concerning system parameter specifications which leads to design the excellent digital controller. The proposed scheme is simulated by MATLAB and the results confirm foregoing claims.
