平台式惯性测量系统车载试验设计

Vehicle Test Design of Platform Inertial Measurement Units

根据平台式惯性测量系统的实际情况,简化了惯性测量误差模型,推导了平台式惯性测量系统误差观测方程,并进行了车载试验的试验设计。在输入设计中,通过仿真分析给出了降低系统复共线性的几个条件。在输出设计中,选定了系统的测量量,确定了传感器的类型及安装方式。

According to the practice of vehicle test of platform inertial measurement units, the error model of inertial measurement units was simplified, and the error measurement equations were deduced. The test design of inertial measurement units' vehicle test was designed. In the input design, some requisitions for deducing the multi-colinearity was given through simulation analysis. In the output design, the measurement variance and the sensors' style and fixing manner were determined.
