摘要
为了增强MEMS(Micro Electromechanical System)陀螺抗外部角运动干扰能力,利用欧拉动力学理论,采用解析法构建了动态误差数学模型,分析了各误差的物理起因及影响大小。通过系统误差标定、补偿试验,计算基于MEMS惯性器件的微小型捷联惯性导航系统的动态误差。采用仿真方法验证了该系统应用于反坦克弹的可行性。
In order to improve the anti-jamming ability and precision of MEMS gyroscope, the physical causes of error were analyzed. The dynamic error mathematical model was constructed using the dynamic theory and analytic method. The dynamic error of micro strap-down inertial navigation system was obtained through the test of calibration and compensation. The feasibility of project which the system used to anti-tank missile was verified through system simulation method.
