Design and implementation of Generalized Proportional Integral controller for buck Converter

Abstract

This Paper present the GPI Controller for Buck converter. Average control signal is derived ,in order to achieve the good stability of the converter and it's response is compared with the PID controller in terms of delay time td, rise time tr, peak time tp, Maximum peak overshoot Mp, and settling time ts, to ensure the robustness of the GPI controller. In order to improve the transient response and dynamic Performance of the converter, the controller parameters are designed based on voltage mode control. The design is evaluated and verified using MATLAB/Simulink. Experimental setup has been done to evaluate the controller platform.
