Temperature Error Modeling Study for Laser Gyro

摘要：

This paper points out that the laser gyro scale factor is relevant to temperature,temperature increment and temperature rate. Temperature error models of the laser gyro scale factor are set up by the two ways of BP network identification and of Least-Square approximation. BP network identification can approach the nonlinearity of laser gyro scale factor temperature model arbitrarily, and can earn higher precision. Mean squared deviation of the model using BP network identification is smaller than 6.1 × 10-7(/pulse). The Least-Square approximation is simpler, and it is propitious to insure the real-time performance of the system.
