| Abstract: | Based on the basic idea of adaptive varia bl e structure control (AVSC), this paper deduces the reaching cond ition of sliding-mode, and proposes three laws according to which the slope of a switching line change, that is, linear law, power law and index law. In additio n, three modes of switch functions are designed according to above laws. Finally , a simulation example is illustrated to study the switch functions, and the sim ulation result shows that the system that adopted square law has the best contro l effect. |
