Advanced Control of Buck-Boost Converters with a GEO-Tuned TI(1+PD) Controller for Design Insights and Performance Optimization

This paper highlights the problems involved in the realization of transient performance, stability, and robustness in DC-DC buck-boost converters that traditional control methods are unable to achieve when the system is under dynamic conditions. Our suggested solution is a TI(1+PD) controller, which is optimized by using golden eagle optimization (GEO), to handle the problems. The TI(1+PD) controller has the dynamics of the tilt-integral and a proportional-derivative control structure that is easy to calculate yet increases the control performance. The simulation results demonstrate that the proposed controller has an acceptable level of overshoot reduction, enhanced settling time, and increased robustness to perturbations and component uncertainties, in comparison with the conventional proportional-integral (PI) and proportional-integral-derivative (PID) controllers. The aforementioned developments constitute the T I(1+P D) controller as a fascinating option in the field of contemporary power electronics and thus, the expansion of power systems that are both efficient and reliable is facilitated.
