摘　　要：基于自适应变结构控制的基本思想,推导了自适应滑模的到达条件,并提出了切换线斜率变化的三种规律:线性规律、幂次规律和指数规律,设计了相应形式的切换函数。最后,举例进行仿真研究,仿真结果说明:采用二次幂规律的切换函数控制效果最佳。Based on the basic idea of adaptive variable structure control (AVSC), this paper deduces the reaching condition of adaptive sliding-mode, and proposes three laws according to which the slope of a switching line change: linear law, power law and exponential law. In addition, three forms of switching functions are designed according to above laws. Finally, an example is researched by simulation, and the simulation result shows that the switching function that adopted square law has the best control effect.
