| 摘 要： | 针对一类不确定离散系统,提出了一种变速率滑模控制方案.通过使用变速率采样技术,设计了用于同时估计系统状态和干扰的混杂观测器,并据此发展了滑模控制器,确保取得准滑动模态的同时,消除了对不确定项的线性边界条件要求.仿真结果验证了所提方法的有效性.

| Abstract: | This paper proposes a multi-rate sliding mode control scheme for a class of uncertain discrete-time systems.By using multi-rate sampling technology,a hybrid state and disturbance observer is proposed to estimate the system states and disturbance.Based on the observed states and disturbances,the sliding mode controller is designed to achieve quasi-sliding mode,thus removing the linear boundary conditions of the uncertainties. |
