摘要
以Boost变换器为研究对象,研究了其产生混沌的现象及机理,并分析了在一定的参数条件下,混沌现象的产生及系统平衡点对混沌现象的影响。为了有效地控制Boost变换器中的混沌,使其获得良好的性能,本文从能量平衡的角度提出了一种非奇异终端滑模控制策略对其进行控制,使得Boost变换器的电压、电流在有限时间内收敛,并将此方法与普通线性滑模控制进行对比研究,最后通过仿真和实验表明了所提控制策略的有效性和正确性。
This paper studied the phenomena and mechanism of chaos generated in Boost converter firstly, and from the point of view of certain parameters, the reason of chaos generation and the influence caused by balanced point is analyzed. In order to control the chaos phenomena effectively, a non-singular terminal sliding mode （NTSM） control method based on the energy constant is proposed. Meanwhile, the superior properties of NTSM compared with the traditional linear sliding mode （LSM） control are presented. Finally, the simulations and experiment verify the effectiveness and correctness of the proposed strategy.
