Newton
说明: 用牛顿下山法求解方程:下山因子在计算过程中可以变动,一般选择下山因子时从1开始,逐次将减半进行试算,直到能使下降条件成立为止。若当计算到某步时取不到满足要求的值(或值小到无法容忍),这时称“下山失败”,需要另取初值重新算起。(Descent method with Newton' s equation: down factor in the calculation process can change, usually selected from the 1 start down factor, will be halved for successive spreadsheet until the can down the conditions established. If when calculating the time to take a step not meet the requirements of the value (or values ??too small to tolerate), then the " down failed" , you need an alternative initial re-counting.)

This function uses eigenfunction analysis to solve the matrix differential equation
m*y (t)+c*y (t)+k*y(t)=f1*cos(w*t)+f2*sin(w*t)
with initial conditions of y(0)=y0, y (0)=v0

B747_simulink_Model
以波音747为背景,建立了飞机运动的空间六自由度仿真模型。其中包含以下部分:
1. 飞机运动的空间六自由度仿真模型
2. 自动驾驶仪仿真模型;
3.执行器仿真模型;
4.大气重力环境模型;
5.气动数据模型;
6.发动机推力模型;
另外,仿真过程中:
1.考虑了风场的影响
2.考虑了传感器的随机噪声;
3.考虑了执行器时间延迟;
4.采用变增益控制器;
状态方程选取:速度、攻角、侧滑角、机体系三轴角速度、欧拉角、地面坐标系坐标作为状态量;
输出方程有:12个状态量;12个状态微分值;以及机体系速度、加速度、过载等。
仿真程序见附件,需Matlab2007b及更高版本运行。
