| 摘 要： | 提出一种鱼雷传感器故障在线诊断方案，直接利用各传感器测量值导出解析余度，通过统计假设检验，完成故障的检测和隔离。由于无须增加硬件余度和其他解析余度，因而易于实现，且可靠性好，检测迅速。仿真结果验证了该种方法的有效性。

| Abstract: | Proposes a scheme for the on-line sensor failure diagnosis of torpedo sys-tems.Measurements of sensor outputs are utilized to generate analytical redundancy,and the task of failure detection and isolation is fulfilled through statistical hypothesis testing.This method needs no additional hard redundancy or any other type of analyti-cal redundancy.Yet it is easily implemented,has a high reliability and gives out a fast detection.Effectiveness of this scheme has been verified by extensive computer simula-tions. |
