Robustness Analysis of Sliding Mode on DC/DC for Fuel Cell Vehicle
Robustness Analysis of Sliding Mode on DC/DC for Fuel Cell Vehicle is a scholarly work, published in 2013 in ''Journal of Engineering Science and Technology Review''. The main subjects of the publication include electronic circuit topology, lithium-ion battery, electric vehicle, proton exchange membrane fuel cell, MATLAB, biological robustness, fuel cell, voltage, boost converter, automotive engineering, forward converter, sliding mode control, DC-to-DC converter, control theory, and engineering. The energy conversion efficiency of fuel cell electric vehicle is high.However, the output characteristics of the current fuel cell tend to be weak and the output voltage fluctuation is apparent, so the DC/DC converter is used for voltage matching and transformation.Through the study on the characteristics of fuel cell in this paper, the main function and topology structure of the on-board DC/DC converter in fuel cell electric vehicle is introduced and the sliding mode control structure is established according to sliding mode control theory.The simulation of the sliding mode controller is performed by MATLAB.The simulation results show that, under the changes in input voltage and load, the fast response and stable output of the on-board DC/DC converter in fuel cell electric vehicle can be realized.
