【摘要】 基于MEMS传感器设计了面向机载惯性稳定云台的微姿态参考系统。首先,对磁力计受到的环境干扰磁场的影响进行了信号补偿;然后,在分析角速度陀螺、加速度计和磁力计等传感器特点的基础上,提出一种新的卡尔曼滤波算法模型;最后,通过性能测试,验证了微姿态参考模型具有较好的静态和动态性能,完全满足机载惯性稳定云台的需求。更多还原

【Abstract】 The mircor-attitude referrence systme (MARS) for the inertia stabilised Pan-tilt system is designed by the MEMS(Micro Electromechanical System) sensors.Firstly,the magnetometer is compensated about the disturbance magnetic field.Secondly,the new model of Kalman filter is setup based on the analysis of characteristic of gyro、accelerometer and magnetometer.Finally,the MARS is testified to have a good static and dynamic performance by the test.更多还原
