資料介紹

針對在轉向控制過程中，需要得到運動對象運動的角速率與轉角，設計了基于LMS8962 ARM 微處理器與CRS10高精度數字式陀螺儀的角速率與轉角測量系統，描述了CRS10的功能特點及使用方法，闡述了系統設計的原理，并給出了系統設計的硬件電路和軟件設計流程。最后將其與Crossbow Technology公司的高精度IMU AHRS500GA-226航向參考系統測得的結果進行對比分析。實驗結果為：角速率測量誤差平均為0.550 （°）/s，轉角測量誤差還比較大，平均誤差為2.5°，測量精度有待進一步提高。

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
