离散滑模控制器的设计及其应用

Design and Application of a Discrete Sliding Mode Controller

针对ＳＩＳＯ离散系统，介绍一种离散滑模控制策略。并利用离散李亚普诺夫函数法导出系统稳定的条件。将其应用于交流伺服系统的速度环中，仿真结果证实了这种离散滑模控制策略的有效性及其优良控制性能。

A discrete sliding mode variabe structure control strategy for a single-input/single-out-put discrete system is described.The stability conditions are derived using a discrete Lya-punov function.A discrete sliding mode controller based on the strategy has been designedand used in an indirect vector-controlled AC servo system.Results of simulation have provedthe effectiveness and good control performance of the control strategy proposed
