Performance Analysis of Classical Control Methods for Optimized Response in Buck Converters

To optimize efficiency and stability, the installation of exact control techniques is necessary in buck converters, as they very the key elements in effective conversion of DC voltage. This study investigates various classical controller tuning methods to enhance the performance of converters. The OLTR methods, UC methods, and the EPI methods are effectively implemented on the chosen benchmark transfer function system of the buck converter. This research evaluates the simulation outcomes based on time transient response metrics, namely delay time, rising time, peak overshoot, peak time, and settling time. Furthermore, frequency responses based on Bode plots are examined to evaluate the stability of the transfer function of the applied control techniques. This article concludes by inferring that the WJC method is the most suitable method for achieving greater stability, minimum overshoot, and improved steady-state control.
