Bias of ring laser gyro (RLG) changes with temperature in the non-linear way, which is an important restraining factor for improving the accuracy of RLG. For the deficiency of least squares regression and neural networks, a new method of temperature compensation of RLG’s bias was proposed, that is, building function regression model by using Least Squares-Support Vector Machine(LS-SVM). Static and dynamic temperature experiments of RLG’s bias are carried out. The results show that: after static temperature compensation, the maximum error of RLG’s bias has dropped from 0.0413º/hr to 0.00073º/hr; while after dynamic temperature compensation, the gyro precision has increased fromσ= 0.0102º/hr toσ= 0.0011º/hr. It indicates that this method has improved the laser gyro’s accuracy considerably. Introduction As one of the core device of strapdown inertial navigation system, mechanically dithered RLG, with a series of advantages of short start-up time, wide dynamic range, and digital output and so on, is widely used in many cutting-edge military fields. For practical gyro of engineering, the general requirement is wide work temperature range. As an important indicator of measuring the performance of RLG, bias stability is impacted greatly by temperature. Therefore, in order to further improve the RLG’s precision, the most effective way is to establish a temperature model of RLG’s bias through experimental analysis, and make real-time compensation. At present, the commonly used method of temperature compensation is to get curve fitting parameters by using system identification methods such as least squares regression analysis based on experimental data for establishing temperature compensation model. However, for complex non-linear data fitting, this traditional modeling method is limited. In recent years, many scholars suggest to establish a model showing gyro’s change with temperature by using non-linear regression of neural network[1]. However, the neural network does not have support of a complete mathematical theory, and there are problems such as local minimum, over-learning and others. In 1990s, Vapnik and others has studied and developed a machine learning algorithms based on statistical learning theory - Support Vector Machine (SVM), which seeks the best compromise between complexities and learning ability of a model according to limited sample information, in order to obtain the best generalization ability[2]. SVM has intuitional geometric interpretation and perfect mathematical form, which can overcome the weakness such as local minimum and over-learning. It had been applied in pattern recognition, regression forecast, nonlinear control and other areas. However, in application of the standard SVM algorithm, there is a problem of hyperplane parameters selecting, in addition, matrix scale in solving quadratic programming problems is impacted greatly by numbers of training samples, which results in the over-large solving scale problem. Least Squares-Support Vector Machines (LS-SVM) proposed by Suykens et al. starts with loss function of machine learning, uses two norm in objective function of its optimization, and replace inequality constraints of SVM standard algorithm with equality constraints, which converts optimization problem of LS-SVM method to a solution of a set of linear equations through
