| Abstract: | The Grey prediction model theory(GM 1,1) is introduced to fault detection of underwater vehicle sensor.Firstly,the grey model is presented with sensor data of underwater vehicle;Secondly,according to the analysis of error between the output of grey dynamic prediction model and the practical sensor output signals,the sensor fault is diagnosed.The fault diagnosis method is applied in three kinds of fault patterns of compass sensor for Outland 1000 ROV.The result of the experiment proves that the proposed meth... |
