| 摘 要： | 分析了工作在电流断续状态下BOOST变换器的离散迭代模型,对该迭代模型的分岔现象进行了仿真研究。基于MATLAB的POWER SYSTEM工具箱,采用基于器件模型的仿真研究证实了该变换器中的混沌现象。针对该混沌现象采用了跟踪控制方法进行控制,该方法消除了变换器中的混沌现象,使变换器工作在周期1状态,基于迭代模型和器件模型的仿真结果表明了混沌现象的存在和所提控制方法的有效性。

| Abstract: | the discrete iteration model of BOOST converter in Discontinuous Conduct Mode is studied, whose bifurcation phenomenon is researched by simulation. Chaos is confirmed by the simulation result using device model based on the POWER SYSTEM toolbox of MALAB. The tracking control method is proposed to control the chaos in BOOST converter. This method eliminates chaos in the converter and forces the converter working in period 1 mode. Simulation results based on both iteration model and device model show the existence of chaos in BOOST converter and the effectiveness of the proposed method. |
