Novel Controller for DC-DC Cuk Converter

Many applications like hybrid electric car and renewable energy use cuk dc converter. The controller of cuk dc converter is important to ensure that the system works in stable region with all small and large disturbances. In this study, different types of controllers are used for cuk converter. These controllers are PI, PID, and Novel controller type tuning by using SISOTOOL MATLAB. The comparison between controllers are investigated in this study. In addition, the effect of internal resistance Ron of switching power devices on the control performance are taken in to account. Furthermore, the impact of parasitic components of cuk converter on the feedback controller is considered in this study. Moreover, in this paper, the impact of variable input voltage on the circuit performance is studied. The impact of Variable reference voltage on control performance is invetgated. The research results that the Novel controller by using SISOTOOL MATLAB has best performance and more robustness than conventional controller with small and large disturbance.
