摘要:
针对在基于MEMS加速度计的磁浮列车速度计算方案中加速度计的误差导致车辆速度计算不准确问题,提出了一种新型的误差标定方法。首先,从安装误差和固有误差2个方面建立了加速度计的误差模型;其次,针对安装误差模型提出了基于自适应阻尼最小二乘的安装误差在线求解方法;最后,在某国产中低速磁浮列车上进行了现场试验。试验结果表明,文章提出的方法可以有效地对加速度计的误差进行标定,可以满足磁浮列车速度计算需求。
Abstract:
For the error of the accelerometer leads to inaccurate calculation of the vehicle speed in the MEMS accelerometer-based maglev train speed calculation scheme, a new method of error calibration was proposed. Firstly, the error model of the accelerometer was established from two aspects: installation error and inherent error. Secondly, an online solution method based on adaptive damped least squares was proposed for the installation error model. Finally, a field test was carried out on a domestic medium-low speed maglev train. The test results showed that the proposed method can effectively calibrate the error of the accelerometer, and can meet the speed calculation requirements of maglev train.
