针对小型化激光陀螺捷联惯导系统(SINS),建立了四种不同的温补模型,分析和对比了包含高温、低温和变温三种不同温度模式下的温补效果。试验结果表明:温度变化率是影响惯性器件误差的重要因素,考虑温度和温变率模型的动态模型温补效果明显优于单纯考虑温度的静态模型。另外,为了检验小型化SINS的稳定性以及温补模型与时间的关系,5个月后再一次对其温度特性进行研究,结果表明:SINS稳定性良好,温补模型基本不受时间影响,满足工程应用的需求。
According to SINS, four different models of temperature compensation are established, and the effects of temperature compensation are analyzed and compared under three different temperature modes including high temperature, low temperature and variable temperature. The experimental results show that the rate of temperature change is an important factor affecting the error of inertial devices. The dynamic model with temperature and temperature change models is better than the static model with temperature alone. In addition, in order to test the stability of miniaturized SINS and the relationship between temperature-compensated model and time, the temperature characteristics of the SINS miniaturized after 5 months were studied again. The results show that the stability of SINS is good and the temperature-compensated model is not affected by time. Engineering application needs.
