摘　　要：为了研究离散变速趋近律的稳定参数区域,依据离散变速趋近律滑模的特点,得出了离散变速趋近律渐近稳定的充分条件,依照此条件获得了变速趋近律各个参数的具体范围,进而提出了广义离散变速趋近律的概念,同时也给出了其保证系统稳定的参数范围,设计了两个离散系统的广义变速趋近律的控制方案。仿真结果表明,得出的参数范围能保证系统渐近稳定。This paper aims at the stability parameters of the variable rate reaching law （VRRL）. Based on the analysis of the characteristic of the VRRL, the sufficient condition of the asymptotic stability of the systems is obtained. Then the domains of the parameters are deduced under this condition and the notion of general VRRL is proposed. Two examples are designed and the simulations demonstrate the effectiveness of the parameters, which guarantee the asymptotic stability.
