The Design and Application of Boost DC Converter Power Sliding Mode Controller

摘要

A strategy which connects the pulse width modulation with sliding mode control is put forward and a boost DC converter sliding mode controller in continuous current mode is designed, using DC-DC conversion technology that changes the single low-voltage lithium battery of 3.2V into the working power station of 12V. Building the controller simulation model in Matlab / Simulink environment, simulating controller performance in the case of changing the load resistance and input voltage; Simulation results validate its performance in the large-scale disturbance, and show its good dynamic performance, robustness, and smaller steady-state error.
