Laser Gyro Temperature Error Modeling And Compensation Study

Laser gyro become of new generation inertia rational component of navigation system gradually already with good performance characteristics and a great deal of advantage their. This text carries on the analysis and modeling to the temperature error in the laser gyro inertia navigation system. Have derived the standard method of the error that the inertia of adopting the laser gyro makes up according to the navigation system standard method of error coefficient of general inertia, make to laser gyro inertia up and test the temperature error on the basis of the thing that the error is marked and reserved, the scale factor and top to the laser gyro drift about, etc. The data of error caused by temperature carry on the record. Put in order, compare, analyses it on the basis of data gathered, put forward based on the artificial neural network BP network model carry on method that data fit is it study temperature impact on error relation to come, thus set up error model then compensate.This text has discussed in adopting the method that BP network carried on the data and fitted, train such impacts on BP network performance of the factor as the method, etc. after studying network structure, every parameter, network. Have improved network structure according to the needs of question on the basis of single importing and single outputting network model, combine the factor influencing the laser gyro error and expand the structure of the network to two-dimensional structure, as to making better result with single inputting models. Finally, some questions in the project is used of this method are discussed to which will offere certain experience and reference for further work in the future.
