故障诊断，包络解调分析，对于轴承故障诊断非常有效(Fault diagnosis, envelope demodulation, very effective for bearing fault diagnosis)

数模源程序，港口模拟源程序，正在学数模的可以下载，到时直接应用，或者借鉴。。。(Digital-analog source, port analog source, is learning digital-analog can be downloaded, when applied directly, or draw. . .)

power flow for 69 distribution system

The zip file contains several matlab files. These files implement the optimal vlassifier (optimal_classifier.m), a sub-optimal classifier (SOS_STBC_Classifier.m) which is based on Second Order Statistic and a low-complexity sub optimal code-parameter classifier (CP_Classifier.m). See reference [1] for the theoretical background. Example: To create the fig 3,4 and 5 of the paper, call the routine: Blind_recognition_STBC2_simulation_results(512,4, PSK ,4) Reference: [1] V. Choqueuse, M. Marazin, L. Collin, K. Yao and G.

本程序的功能是用牛顿－拉夫逊法进行潮流计算(This program function is to use Newton- rafer Johnson flow calculation method.)

异步电机的矢量控制，详细的介绍了异步电机矢量控制系统建立的过程，以及仿真结果(Induction motor vector control, a detailed description of the induction motor vector control system established process and simulation results)

： 针对粒子群优化算法易陷入局部极值的缺点， 提 出一种改进粒子群算法， 该算法借鉴贪婪算法的思想初始化种群， 利用两 个种群同时寻优， 并将遗传算法中交叉和变异操作引入其 中， 实现种群间的信息共享。(I n a l l u s i o n t o p a r t i c l e s wa r m o p t i mi z a t i o n b ei n g pr on e t o g e t i n t o l oc a l mi n i mu m， a n i mpr o v e d p a r t i c l e s wa r m o pt i mi z a t i o n a l g o r it h m i s p r o po s e d． Th e a l g o r it hm dr a ws o n t h e t hi n ki ng o f t he g r e e d y a l g o r it hm t o i n i t i a l i z e t he pa r t i c l e s wa l- n 1 ． Two s wa r ms a r e u s e d t o o pt i mi z e s y nc h r o no u s l y， a nd c r o s s o v e r a n d mu t a t i o n o p er a t o r s i n g e n e t i c a lg o r i t h m a r e i n t r o d uc e d i n t o t h e ne w a l g o r it h m t o r e a l i z e t h e s ha r i ng o f i n f o r m a t i o n a mo ng s wa r l T i S ．)

Any change to the value of Mresults in immediate and phase-continuous changes in the output frequency

异步机直接启动最基本的仿真模型，希望对大家有用(Asynchronous machine directly start the basic simulation model, we hope to be useful)
