| 摘 要： | 针对多个传感器同时对动态系统测量，且输出数据包含实时测量值和延迟测量值的情况，给出约束滤波算法。在处理延迟测量信息时，利用两个递归的滤波器实现状态估计的更新，避免了状态扩维，节省了计算时间。计算机仿真说明了新方法的有效性。

| Abstract: | In this paper,the constrained estimate result is extended to the situation with both current and delayed measurements.Filtering of delayed measurements is achieved by using two recursive structures that reduces the computer burden because of the avoidance of the system augmentation.Simulation shows performance advantages of the proposed algorithm. |
