State Observer-based Sliding Mode Control for DC-DC Boost Converter
摘要
Abstract
To track the reference voltage value,an state observer based on sliding mode control was designed for pulse width modulation based on DC-DC Boost converter subject to the change of input voltage and load resistance. The real-time values of the load resistance and input voltage were estimated through the state observer using the law of estimation. The control algorithm was obtained by sliding mode surface which was designed using the estimated information and the exponential reaching law. Through rigorous analysis,the stability of closed-loop system of Boost converter was proved. Matlab simulation verifies the effectiveness of the proposed control algorithm,and compared with the nominal sliding mode control method,the proposed method has better robustness.关键词
