Cascaded Integral-Retarded Control of Switched DC-DC Boost Converters

https://doi.org/10.58571/CNCA.AMCA.2025.029

Resumen: In this paper, we explore the use of a delay-based control scheme consisting of two Integral-Retarded (IR) controllers arranged in a cascaded architecture for regulating a DC-DC boost converter. The proposed control scheme utilizes an inner-current loop that adds damping by feeding back the inductor current, and an outer-voltage loop that regulates the converter’s output voltage. Specifically, both inner and outer IR controllers are designed to improve the dynamic response during load and input voltage changes while attenuating highfrequency measurement noise. Tuning formulas are derived by assigning a triple real dominant root to the closed-loop system. Simulation results show better robustness properties compared to the traditional cascaded Proportional-Integral (PI) control scheme, showing the effectiveness of the delay-based approach.
