摘　　要：为了提高飞行仿真的置信度,设计了一种由解算模型和误差模型组成的机载挠性陀螺传感器仿真模型。根据从飞行状态、环境仿真软件输出的物理量,推导出传感器输出量物理意义上的解算表达式,并利用MATLAB/SIMULINK建立其解算模型。分析挠性陀螺技术指标来表征的误差以及工作环境变化导致的传感器误差,建立挠性陀螺的误差模型。通过仿真测试,证明此模型有效实用,对完善飞行仿真有很大的帮助。In order to improve the confidence of flight simulation,a simulation model for airborne flexible gyroscope sensor is designed,which consists of solution model and error model.According to the physical quantity output from flight state and environment simulation software,the physical expression of sensor output is deduced,and its solution model is established by using MATLAB/SIMULINK.The error of flexible gyroscope technical index and sensor error caused by the change of working environment are analyzed,and the error model for flexible gyroscope is established.Simulation test proves that the model is effective and practical,which is very helpful to improve flight simulation.
