摘要
研究了系统含有未知扰动时的状态估计问题,提出了一种新的状态估计方法,它能消除未知输入干扰,给出了新型状态估计器存在的条件。仿真结果证明了本文的正确性。
This paper deals with the problems of the state observers for linear systems with unknown input disturbances. A new kind of observer is presented here. It can reject unknown input disturbances. Then, the necessary and sufficient conditions for such an observer are given. Finally, an illustrative example is given to verify the results of this paper.
