摘要: 研究了含不确定输入的线性奇异时滞系统的观测器设计.在一定秩条件下,通过引入 两个广义坐标变换,先将系统等价变换为不含不确定输入的正常状态空间时滞系统,再变换为 在系统描述中滞后项仅与输入和输出有关的系统.通过设计等价系统的状态观测器来获得原系 统的观测器,实现对原系统的状态与不确定输入的指数逼近.Abstract: The observer design for linear singular time-delay system with uncertain input is studied. Under some rank conditions, two generalized coordinate changes are introduced to transform the singular time-delay system into an equivalent normal system without uncertain input, then into a system with time-delay terms associated with the input and output only in the system description. The observer for the original system is obtained by designing the state observer for the equivalent system to realize the exponential approximation to the state and uncertain input of the original system.
