Description: 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.

[Other Games] ball

Description: 该程序用不同颜色的小球的运动轨迹来画出一幅抽象图画。小球共有七个，分别是红，绿，蓝，黑，白，靛青，橙黄色。小球在画布的上方分别间隔相等的距离，同时出发，但各个球的运动速度是逐渐减少的。第一个球最快，从第一个球到第六个球速度逐渐递减，且球的运动方向是逆时针，第七个球是顺时针运动。球的运动轨迹模拟光的反射。以边界的法线为对称轴的对称直线，即小球运动轨迹直线的入射角度等于反射角度。-The program with a different color ball trajectory to draw an abstract picture. Seven balls were red, green, blue, black, white, indigo, orange and yellow. The top of the canvas ball equal distance intervals, respectively, on the same flight, but each movement of the ball speed is gradually reduced. The first ball the fastest, from the first ball to the sixth ball speed gradually decreases, and the direction is counterclockwise movement of the ball, the ball is the seventh clockwise movement. Simulation of the trajectory of the ball of light reflection. Normal to the boundary line for the symmetry axis of symmetry, that is a straight line trajectory the ball incident angle equal to the reflection angle.
