This paper presents the nonideal model and Type III compensator-based control system design for DC-DC Cuk converter. The proposed nonideal model considers practical imperfections, including parasitic resistances of inductor and capacitor, as well as voltage drops across the MOSFET and diode, to accurately reflect operational operating conditions. The state-space averaging technique is employed to derive the small-signal transfer function of the system. Subsequently, a Type III compensator is implemented to enhance system stability and dynamic response. The effectiveness of the proposed nonideal model and control strategy is validated through Software In The Loop (SIL) simulations conducted on the MATLAB platform, demonstrating its capability to regulate output voltage and improve transient response under a range of load conditions.

摘要

This paper presents the nonideal model and Type III compensator-based control system design for DC-DC Cuk converter. The proposed nonideal model considers practical imperfections, including parasitic resistances of inductor and capacitor, as well as voltage drops across the MOSFET and diode, to accurately reflect operational operating conditions. The state-space averaging technique is employed to derive the small-signal transfer function of the system. Subsequently, a Type III compensator is implemented to enhance system stability and dynamic response. The effectiveness of the proposed nonideal model and control strategy is validated through Software In The Loop (SIL) simulations conducted on the MATLAB platform, demonstrating its capability to regulate output voltage and improve transient response under a range of load conditions.
