摘要: 利用滑模控制的概念,提出一种线性离散时变系统的自适应控制设计方法.在等价 控制信号外,用两个补偿项代替切换信号,避免了传统滑模控制中的抖动现象.文中证明了自 适应闭环系统的稳定性.Abstract: Based on the concept of sliding mode control, a design method of adaptive control for linear discrete time-varying systems is proposed. Besides the equivalent control signal, two compensating terms are applied instead of switching signal so that chattering in traditional sliding mode control is avoided. Stability of adaptive closed-loop system is proved.
