求时间序列的最大李亚普诺夫指数，很好用。(the largest lyapunov)

采用最小二乘原理，进行了伪距单点定位计算；包含广播星历计算计算卫星坐标，地固系与WGS84坐标系间转换，最小二乘平差计算，定位几何因子GDOP等(Using least square method, we carried out pseudorange single point positioning calculation contains satellite ephemeris calculation calculate coordinates secured between the system and the WGS84 coordinate system conversion, least squares adjustment calculation, location and other geometric factor GDOP)

说明：  用MATLAB仿真PID控制，其中用simulink建仿真模型，用matlab语言编写PSO算法用于优化PID参数整定。(Matlab is used to simulate PID control, in which Simulink is used to build simulation model, and PSO algorithm is written in MATLAB language to optimize PID parameter setting.)
