Based on the formula, a method for assessing reliability of initiating explosive devices with small sample size is established. Compared with the assessment method for devices with large sample size, the new method is correct and feasible and can be used to assess the reliability of initiating explosive devices with high reliability requirements.展开更多

It has not been solved satisfactorily at present. The complexity of spot welding process, invisibility of nugget formation and singleness of control method decide that stabilizing quality is a rather difficult task. The limitations of describing how the nugget grows up based on single-sensor information source are analyzed. A control method based on multi-information fusion for the purpose of equivalent heating of each weld nugget during spot welding is put forward. The experiment results show that nugget size flactuations are within 8.3% -20% uacter constant current control, and are within 6. 3% - 11.1% under information fusion control.展开更多

In this paper, measurement and correction equations for a single-star stellar-inertial guidance system were developed, and a concept of equivalent information compression was presented and discussed through some propositions. With this concept, accuracies of single/double star schemes were compared, and it was shown that a single-star scheme can achieve the accuracy equivalent to a double-star scheme. This theoretically proves the feasibility of the rapid determination of the optimum stellar direction of the single-star scheme. Lastly, a compensational method to correct the guidance errors was employed when the adopted navigation star deviated from the optimum stellar direction.展开更多

文摘以一类非线性多传感器动态系统为对象,基于扩展Kalman滤波器(Extend Kalman filter,EKF)介绍三种典型非线性集中式融合算法,并以此为基础研究部分线性动态系统融合理论在非线性系统中的推广与完善.首先,利用EKF的一种信息滤波器形式(Extend information filter,EIF)给出测量值扩维融合、测量值加权融合和顺序滤波融合算法公式,进而研究三种非线性融合算法的估计性能比较以及测量值融合更新次序是否满足可交换性.结果表明:当各传感器的测量特性相同时,集中式测量值扩维和测量值加权融合算法的估计精度功能等价;非线性顺序滤波融合与其他两种融合算法之间不再具备线性多传感器系统中估计功能的完全等价特性;在融合精度不变前提下非线性顺序滤波融合中,各传感器观测更新次序不再完全满足可交换性.4个基于纯方位目标跟踪的数值仿真被用来验证文中所得结论的有效性和正确性.
