中文说明：利用粒子群算法进行参数辨识，该粒子群算法经过改进，收敛效果好.有部分需要改进的你可以在自己电脑上进行相应的修改调试。
English Description：
Using particle swarm optimization algorithm for parameter identification, the particle swarm optimization algorithm after improvement, convergence effect is good. Some need to be improved, you can modify the corresponding debugging on your computer.
