摘要:
针对三轴磁传感器与加速度计组合对于弹体的姿态测量存在难以消除或补偿掉有害加速度的问题,设计了一种磁传感器组合的布阵方式。两磁传感器成一定角度安装,并根据传感器布阵方式提出了两种新的解算方法,即零交叉法和极值比值法,使之适用于有线加速度的载体。推导了磁场在磁传感器敏感轴方向上的数学表达式,论证了两种解算方法并进行了数值仿真,在此基础上比较了两种方法,并分析了其误差产生的原因。结果表明:两种方法均适用于高转速弹体横滚姿态和转速的测量;与零交叉法相比,极值比值法获得的姿态角信息多且是单值的,解算的姿态角更为准确
Abstract:
In allusion to the problem that the harmful acceleration consisting of a three-axis magnetic sensor and accelerometers on projectile to measure attitude angles is difficult to remove or compensate,a new scheme comprising magnetic sensors installed in a particular way is designed.Two novel calculation methods called zero crossing method and the ratio of extremum method are adopted based on the configuration of sensors,make the scheme be applicable for the carrier which has linear acceleration.The mathematical expressions of the magnetic field along the sensitive axis of sensors are deduced,the two novel methods are demonstrated and a numerical simulation is worked out.The comparison of the two methods and the error analysis are given based on the simulation.The result indicates that the roll angle and the axial angular rate can be solved by the two methods.Compared with the zero crossing method,the ratio of extremum method is better,because more information and single value of attitude angles can be obtained,the calculated attitude angles are more accurate,and the errors of the angles are decayed faster.
