Advanced Nonlinear Backstepping Controller for Magnetic Linked DC-DC Converter

An advanced nonlinear backstepping controller is proposed in this paper for magnetic linked dc-dc converter to achieve robust voltage regulation with less settling time and zero steady stare error without any chattering effect. The performance of the proposed controller is tested under different operating conditions, such as variations of load and input voltage, and step change in controller reference signal. The proposed controller provides a control equation with only one gain parameter facilitating easy tuning capability. For comparison purposes, the performance of the proposed controller is compared with the most traditional proportional-integral controller and different nonlinear sliding mode controllers, like no integral sliding mode controller and double integral sliding mode controller.
