Abstract

This paper presents an advanced nonlinear backstepping controller for a magnetic-linked DC-DC converter, designed to achieve stable voltage regulation with zero steady-state error, minimal settling time, and reduced chattering effects. The controller's performance is evaluated under various operating conditions, including step changes in the reference signal, as well as variations in load and input voltage. The proposed controller features only a single adjustable gain parameter, which simplifies the overall design process. The performance of the controller is compared to that of the traditional proportionalintegral controller and other nonlinear sliding mode controllers, such as the double integral sliding mode controller and the no integral sliding mode controller. The results of simulations in MATLAB/Simulink demonstrate that the backstepping controller outperforms existing controllers in terms of overshoot, steadystate error, and settling time. Experimental validation on a scaleddown laboratory test platform further confirms the superior control performance of the proposed backstepping controller for magnetic-linked DC-DC converters.
