| 摘 要： | 基于衰减控制,讨论了离散时间系统的变结构控制问题,提出了衰减指数控制和时变衰减幂次趋近律。理论分析表明该方法能够使系统抖动以指数幂次逐渐衰减,从而消除了稳态抖动,保证了闭环系统的渐近稳定。仿真结果表明该方法是有效的。

| Abstract: | The design of variable structure control for discrete time system based on attenuating control was discussed.The attenuating exponential control and the time-varying attenuating power reaching law were proposed.The theory analysis demonstrates that the proposed methods can make the system chattering decreasingly attenuate at exponential rate.So the stationary chattering is eliminated which ensures the asymptotic stability of the closed loop system.Simulation results show the given method is effective. |
