摘　　要：离散变结构控制设计一般基于系统的状态方程模型,且要求已知扰动量的变化范围,不利于实际应用。文章基于对象差分方程模型,提出了一种离散变结构控制算法,该算法设计无需已知系统内外扰动大小的范围,有利于工程应用,且有利于消除系统的抖动;对所提出的算法进行了仿真研究,结果表明该控制算法具有较好的效果及鲁棒性。The design of discrete variable structure control is generally based on the state equation of the system, and the bound of disturbances should be given, which is inconvenient to practical appplication. A new algorithm of discrete variable structure control is presented based on the discrete inputoutput model of a plant, which overcomes the shortage above mentioned. Digital simulation is carried out, and its results show that the proposed control algorithm is valid.
