混沌状态下Boost变换器参数误差的影响与控制

探讨了混沌状态下变换器对电路参数误差的敏感性,同时对两个具有细小电路误差的变换器进行了混沌同步控制。通过仿真实验,得出了运行在混沌状态下的Boost变换器对电路参数的细小变化极为敏感。因此,在研究混沌状态下Boost变换器的并联运行时,必须针对此敏感特性进行控制。提出了使用混沌同步的方法来抑制混沌状态下Boost变换器的敏感性影响,并设计了具体的控制策略。通过仿真实验,证明了该控制方法能有效抑制Boost变换器的敏感性影响。最后给出了研究结论。

Effect and control of parameter error in chaotic Boost converter

The sensitivity of chaotic converter and the chaotic synchronization of two converter modules were discussed in this paper,which had tiny difference in their system parameters.It shows that the running status of chaotic converter sensitively depends on its system parameter.So,when the researches on chaotic paralleledconverter were performed,the sensitivity must be taken into consideration.The chaotic synchronization method was proposed to control the sensitivity effect,and the specific control strategy was designed.The simulation results show that this method can effectively control the sensitivity effect of Boost converter.Finally,the research conclusion was given.
