| 摘 要： | 本文讨论了陀螺仪起动时的热平衡过程，在陀螺漂移和内部温度，特别是温度的变化率之间建立动态数学模型，并且用广义最小二乘（ＧＬＳ）和递推最小二乘（ＩＬＳ）进行辨识。如果陀螺起动过程良好，就可以用补偿方法缩短惯导系统的准备时间。动力调谐陀螺起动过程的重复试验表明，这种方法是可行的

| Abstract: | The thermobalance process of startup of gyroscope has been discussed . Dynamic mathematic model between the drift of gyroscope and the temperature , especially its change rate inside the gyroscope case has been built and identified with generalized least square(GLS) and iteratively least squares(ILS) methods . It can be expected that a compensating method shoud be used to reduce the preparing time of inertial navigation system if the consistence of startup process is good enough . A repeat test of the startup process of dynamically tuned gyroscope shows the feasibility of this method . |
