摘要
讨论了利用离散趋近律设计离散时间系统的变结构控制问题 ,在衰减控制的基础上 ,提出了衰减变速趋近律和衰减幂次趋近律 .理论分析和仿真结果表明 ,本文所提的方法是有效的 ,既保证了闭环系统的渐进稳定性 ,又大大减少了系统的抖动现象 .
The design of variable structure control for discrete time system using discrete reaching law is discussed. Based on the attenuating control, the attenuating variable rate and the attenuating power reaching law are proposed in this paper. The theory analysis and simulation demonstrate the effectiveness of the methods, which not only retain the asymptotic stability, but also reduce the chattering of the system.
