摘　　要：MEMS器件体积小、重量轻、性能稳定、响应时间快,通常用来测量高旋转弹药的飞行姿态参数。针对传统MEMS捷联惯性测量系统存在量程与精度相互矛盾的问题,本文介绍了半捷联MEMS惯性测量的概念,在此基础上重点设计半捷联惯性测量装置减旋控制电路,该电路为小量程、高精度的MEMS器件提供稳定的测试环境。通过试验证明:该减旋控制电路能够有效减小高旋转弹药对惯性测量装置姿态测量精度的影响。MEMS devices with the characteristics of small size, light weight , stable performance and fast response time are usually used to measure the flight attitude parameters of high rotational ammunitions. Against the fact that traditional MEMS inertial measurement system has the contradiction of range and accuracy, this paper presented the concept of semi-strapdown MEMS inertial measurement and concentrates on the design of anti-rotation control circuit for half-strapdown inertial measurement unit, which provided a stable measurement environment for small-scale and high-precision MEMS devices. Experiment results show that the anti-rotation control circuit can effectively reduce the effect of high rotational ammunition to the measurement accuracv of MIMU.
