【摘要】 微惯性测量单元具有成本低、体积小、功耗低和抗冲击等优点,可以应用在车辆稳定控制、平台稳定及导航控制系统中,具有广阔的市场应用前景。详细介绍了采用三轴MEMS陀螺和三轴MEMS加速度计研制的微惯性测量单元硬件设计,对信号进行预处理、陀螺漂移补偿、降噪等处理。所研制的低成本MIMU经过补偿后零位漂移保持在:X轴、Y轴、Z轴,可以应用到普通导航领域。更多还原

【Abstract】 Micro inertial measurement unit has advantages of low cost,small size,low power consumption,impact resistance and so on,and it can be applied to vehicle stability control,platform stability,navigation and control systems,suggesting a wide application field and good prospect.This paper describes the development of the micro-inertial measurement unit hardware design with useing of three-axis MEMS gyroscopes and three-axis MEMS accelerometer,the signal pre-processing,gyro drift compensation,noise reduction,and other processing.The design of the Low-cost MIMU′s zero drift is kept at on x-axis,on y-axis,on z-axis after the compensation,It can be applied to common Navigation field.更多还原
