针对MEMS(微机械)航姿系统的性能受振动环境的影响，提出了MEMS航姿系统减振设计方案。根据MEMS航姿系统的工作原理，分析了振动环境对MEMS航姿系统的性能影响;基于被动减振设计的原理，设计了航姿系统减振结构，基于振动环境中MEMS惯性传感器的数据特征，设计了一种自适应变步长平滑滤波器用于平滑振动加速度，应用平滑后的加速度信息与MEMS陀螺测得的角速度信息进行融合，实现了振动环境下的姿态解算。MEMS航姿系统的振动环境试验验证了论文提出的减振方案与振动环境下数据处理算法的有效性。

A vibration damping design of MEMS AHRS has been proposed to reduce the effect of vibration environment. The effect of vibration environment on the MEMS AHRS performance has been analyzed based on the working principle of the MEMS inertial sensors. A damping structure of MEMS AHRS has been designed. And a variable step size adaptive smoothing filter used to smooth the vibration acceleration has been designed based on the characteristics of MEMS inertial sensors under the vibration environment. Then, the smoothed acceleration and the gyroscopes’ information were fused to realize the attitude estimation under the vibration environment. The damping design and the data processing algorithm of MEMS AHRS under the vibration environment has been proved by the vibration test.
