16APSK调制的MATLAB实现函数，映射为4+16APSK的星座图(16APSK modulation of MATLAB functions mapped to the constellation 4+16APSK)

说明：  网上的Kalman滤波数据融合示例，此处的特点是添加了详细的注释，并且为了更容易理解和顾名思义，对部份变量和函数名作了修改，使得非常易懂。(An example of Kalman filtering data fusion on the Internet! Detailed annotations are added and some variables and function names are modified to make them easy to understand.)

Mysmo.mdl 永磁同步电机的主程序，可以实现有速度传感器启动运行，和无速度传感器运行。 SMOmodel.m 改进的滑模观测器模型，实现永磁同步电机反电动势的估算。 PFCDCM0hm5 用的是0.5hm的电感，实现220V交流电变换成400V的直流电，电流断续。 由于是仿真，如果要硬件实现的话，除了需要电压采样外，还需要一个输入电压过零检测 PFCCM320percent98k50 用的是5hm的电感，实现220V交流电变换成320V的直流电，电流连续。功率因数可以达到0.98，用的开关频率为50K PFCCM400percent97k50.mdl 用的是5hm的电感，实现220V交流电变换成400V的直流电，电流连续。功率因数可以达到0.97，用的开关频率为50K (Permanent magnet synchronous motor Mysmo.mdl main program, you can achieve the speed sensor up and running, and speed sensors run. SMOmodel.m improved sliding mode observer model permanent magnet synchronous motor back-EMF estimates. PFCDCM0hm5 with is 0.5hm inductor to achieve 220V AC transform into a 400V DC current is interrupted. As the simulation, hardware implementation, then, in addition to the voltage sampling an input voltage over zero detection PFCCM320percent98k50 the is 5hm inductance to achieve transformation 220V AC 320V DC continuous current. The power factor can reach 0.98, the switching frequency for 50K PFCCM400percent97k50.mdl with is 5hm inductance 220V AC transform 400V DC continuous current. The power factor can reach 0.97, with the switching frequency is 50K)

PID控制，可以实现串级系统控制。(PID. The series system control. . . . . .)

蒙特卡洛模拟 散射，不错,适合初学者，不错谢谢分享(Monte carlo simulation of scattering, good)

有限元的MATLAB程序，该MATLAB程序使用有限元法解决连续体的位移及受力问题。使用限制：节点处可受集中力，每一单元可受一个集中力，每边可受一常值边界力(Finite element MATLAB program, the problem of the MATLAB program using the finite element method to solve the continuum displacement and stress. Use restrictions: nodes under concentrated force, every unit can be subjected to a concentrated force, each side by a constant boundary force )

说明：  快速傅里叶变换的应用，可以看一看。。。。。。。。。。。。(fft transform)
