Description: 摘 要:姿态信息是飞行控制中最关键的参数之一,因此姿 态测量成为飞行控制系统首要解决的问题。利用多MEMS 传感器研制了一种微型姿态测量系统。利用三轴MEMS加 速度计和三轴MEMS陀螺数据,由方向余弦矩阵的姿态表 示形式推导了扩展Kalman滤波方程,解算出飞行器的俯仰 角和横滚角;设计专家系统判断飞行器的运动状态,并根据 该状态调整滤波算法中的测量噪声矩阵,使系统可同时满足 静态情况和动态情况的使用;利用空速和高度数据对俯仰 角进行修正,利用GPS解算航向角。将实验结果与国外最新 的商用自动驾驶仪的姿态结果进行了比较,二者在静态情况 下非常吻合,在动态情况下基本吻合。

- The attitude information is one of the most important
parameters in flight control systems. This paper describes an
attitude measurement system based on a MEMS multi-sensor. The
data from 3-axis MEMS accelerators and 3-axis MEMS gyros is used
to determine the pitch angle and the roll angle of the air vehicle using
an extended Kalman filter (EKF) equation deduced from the
direction cosine matrix. An expert system was designed to estimate
the vehicle motion to adjust the measurement noise matrix of the
extended Kalman filter equation so that the system can be used in
dynamic as well as static environments. The measured airspeed and
altitude are also used to revise the pitch angle. The heading is
determined from GPS information. Test results compare well with
an imported commercial autopilot in a static test with less accurate
results in a dynamic test.

Description: 这个zip文件中包含的原则和双方的扩展卡尔曼滤波（EKF）和全球定位系统（GPS）算法简要说明。它的主要目的是提供一个相对容易实现的扩展卡尔曼滤波，在我们使用的输入函数的形式，而不是禁止函数处理符号表达式。它也可作为一个简要介绍了卡尔曼滤波算法GPS和学习它的意思。在为EKF的例子，我们提供的原始资料，同时使用的定位扩展卡尔曼滤波和最小二乘法的任务和解决方案。
有四个M文件和两个数据文件。 Extended_KF.m包含EKF的函数体。另一些功能和GPS的示例数据文件。-This zip file contains a brief illustration of principles and algorithms of both the Extended Kalman Filtering (EKF) and the Global Position System (GPS). It is designed primarily to provide a relatively easy-to-implement EKF, in which we use symbol expressions as the form of input functions rather than the forbidding function handles. It also serves as a brief introduction to the Kalman Filtering algorithms for GPS and a mean of learning it. In the example for the EKF, we provide the raw data and solution for the positioning task using both EKF and the Least Square method.
There are four m files and two data files. Extended_KF.m contains the function body of the EKF. Others are functions and data files for the GPS example.
