Vehicle Integrated INS Test System Design

文章组建了组合式惯导实际的测试系统,采用MATLAB软件验证的EKF控制算法的有效性,通过传感器实测车辆运行数据输入以嵌入式C语言编写EKF的算法程序,通过STM32单片机运行EKF算法进行实际的车辆运行状态参数的准确输出,理论与实际结合完成了测试系统设计,保证了动态测试的准确性,实车运动参数可以为后期电控系统的控制提供更加精确的数据。因此,具有很好的推广价值。

In this paper,the actual test system of the combined inertial navigation system is established.The validity of EKF control algorithm verified by MATLAB software is used.The algorithm program of EKF is written in embedded C language through the input of measured vehicle operation data of sensors.The EKF algorithm is run by STM32 single-chip microcomputer to output the actual vehicle operation state parameters accurately.The design of the test system is completed by combining theory with practice.The accuracy of the dynamic test is verified.The real vehicle motion parameters can provide more accurate data for the later control of the electronic control system.Therefore,it has a good promotion value.
