title = "A High-Order Sliding Model Control Based on Saturation Function of Floating Interleaved Boost Converter for Fuel Cell Vehicle Application",
abstract = "Fuel cells have low output voltage, soft output characteristics, and large voltage fluctuations, so DC-DC converters are usually added to the later stage. These characteristics of fuel cell require high boost ratio and low current ripple. This article adopts a two-phase floating interleaved boost converter, its boost ratio is 1+D times of the traditional boost converter, two inductor currents are interleaved by 180 degrees to reduce the current ripple. The converter is required to be robust because of large fluctuation of the output voltage, random disturbance of the load. Aiming at this problem, this paper proposes a Super-Twisting high-order sliding mode controller based on the saturation function and uses it in a two-phase floating interleaved boost converter. Fuel cell model is used as the input of the floating interleaved boost converter The simulation model of fuel cell steady-state and floating interleaved boost system is built in Simulink. Compared with PI and traditional symbol function Super-Twisting control algorithm, strong robustness and dynamic-steady state performance of the designed controller are verified.",
