Second-Order Sliding Mode Control for Nonminimum Phase Boost Converters With Mismatched Uncertainties

This article presents a novel second-order sliding mode (SOSM) control design and its practical implementation for nonminimum phase (NMP) DC-DC boost converters. Unlike existing controllers, the proposed SOSM controller achieves precise direct voltage regulation for the NMP boost converter with global finite-time stability. Besides, the common chattering problem in sliding mode control (SMC) is avoided using the proposed SOSM control technique. Meanwhile, an outstanding advantage of the SOSM controller is that it can suppress nonvanishing mismatched uncertainty to reduce the burdens in the control input channel. Moreover, the mismatched uncertainty to be counteracted is assumed to be bounded by a much more realistic state-dependent function rather than traditional constants. Finally, rigorous finite-time Lyapunov stability analysis and comparative experiments are performed to verify the feasibility and superiority of the proposed SOSM controller.
