研究了一类带有干扰的非线性离散系统的抗干扰控制问题。针对外部干扰，设计了干扰观测器进行估计；针对系统中的饱和项，设计饱和控制器来消除饱和的影响。在此基础上，提出了基于干扰观测器的控制( DOBC)和饱和的复合控制策略，解决了一类非线性离散系统抗干扰控制问题。

Anti-disturbance control problem was studied for a class of nonlinear discrete systems with disturb-ances. In accordance with external disturbance, a disturbance observer was designed to estimate the disturb-ance. In accordance with nonlinear saturation,a saturating controller was designed to reject the influence of sat-uration. Therefore,a novel type of control scheme combining the disturbance-observer-based control( DOBC) with saturating control was proposed for a class of nonlinear discrete systems with disturbances,and a anti-dis-turbance control problems can be resolved by this control strategy .
