中文摘要
      基于内采样的特性讨论噪声强度不确定的连续系统的鲁棒估计问题，主要目的是为了这类不确定系统设计离散滤波器，使每个状态的估计方差不大于预先指定值，从而获得满意的稳态滤波特性。文中首先研究了仅有模型噪声强度不确定情形，随后说明当测量噪声强度不确定时可用同样的方法进行研究。最后用数值例子说明了本文涉及方法的有用性和有效性。
英文摘要
      In this paper, the problem of robust sampled-data estimation for continuous systems with noise intensity uncertainty is discussed taking account of intersample behavior. The primary purpose of this study is to design discrete filters for this kind of uncertain systems such that the estimation error variance of each state is not greater than a specified value,and therefore the steady-state behavior of the filtering result will be satisfactory.This paper first studies the case that only the intensity of the model noise is uncertain. Then it is shown that the design method in this paper is also suitable for the systems with measurement noise intensity uncertainty. Finally, a numerical example is provided to demonstrate the usefulness and effectiveness of the design method in this paper.
