MATLAB 异步电机变转差率控制 simulink 模型 可供参考(Simlink Model of Variable Slip Rate Control for Asynchronous Motor Based on MATLAB)

迭代自组织数据分析，是本科毕设的题目，使用高阶累积量对MPSK信号进行调制识别。( Iterative self-organizing data analysis, The title of the commercial is undergraduate course you Using high-order cumulants of MPSK signal modulation recognition.)

说明：  自编多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscaleSampleEntropy函数中的SampleEntropy也可以单独拎出来计算单个样本熵。(Multi scale sample entropy is used for a section of bearing fault data, which is easy to understand. SampleEntropy in the MultiscaleSampleEntropy function can also be picked up separately to calculate the entropy of a single sample.)

该代码通过对常规单脉冲雷达信号、LFM雷达信号和BPSK雷达信号通过wiger变换，得到三种信号的时频图，分析他们的时频关系和区别。(The code on conventional single-pulse radar signals, LFM radar signals and radar signals BPSK wiger transformation, three kinds of time-frequency map analysis of their relationship and when the frequency difference.)
