针对在转向控制过程中,需要得到运动对象运动的角速率与转角,设计了基于LMS8962 ARM微处理器与CRS10高精度数字式陀螺仪的角速率与转角测量系统,描述了CRS10的功能特点及使用方法,阐述了系统设计的原理,并给出了系统设计的硬件电路和软件设计流程。最后将其与Crossbow Technology公司的高精度IMU AHRS500GA-226航向参考系统测得的结果进行对比分析。实验结果为:角速率测量误差平均为0.550 (°)/s,转角测量误差还比较大,平均误差为2.5°,测量精度有待进一步提高。
- Abstract:
- In the steering control, angular rate and angle of the object is needed to be measured. An angular rate and angle measurement system was designed based on LMS8962 ARM microprocessor and high?鄄precision digital gyroscope CRS10 in this paper. The features and the use method of CRS10 were described, the system design principle was described, and the system design of hardware circuit and software design flow were given in this paper. Finally the testing results of this system were compared and analyzed with AHRS500GA-226 IMU from Crossbow Technology Inc. Experimental results show that:angular rate mean error is 0.550(°)/s, and angle mean error is 2.5°. The angle measurement precision is needed to be improved
