摘要
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 disturbances.In accordance with external disturbance,a disturbance observer was designed to estimate the disturbance.In accordance with nonlinear saturation,a saturating controller was designed to reject the influence of saturation.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-disturbance control problems can be resolved by this control strategy.
