摘　　要：针对离散系统变结构控制,提出了两个新的滑模趋近律.应用该趋近设计变结构控制系统,其原点的稳定性和系统的平稳性都优于指数趋近律和比例-等速-变速趋近律.通过仿真例子对此进行了验证.Two new reaching laws for discrete-time variable structure control systems are proposed. By applying the proposed control law to discrete-time variable structure control systems, the stability of origin and steady of systems are better than the exponential rate reaching law and proportional-constant-variable rate reaching law. Simulation results show the effectiveness of the proposed control laws.

关 键 词：离散时间系统 变结构控制 滑动模态 趋近律
