混沌保密通信系统的研究，阐述了混沌保密通信系统的发展(Research chaotic secure communication systems, describes the development of chaotic secure communication system)

说明：  变分模态分解方法能够使一个多频带的故障信号，分解出具有单个频带的子信号，然后使用共振解调方法可实现故障信号的诊断。(VMD method can decompose a multi band fault signal into a single band sub signal, and then use resonance demodulation method to realize fault signal diagnosis.)

说明：  本资源为双馈风机DFIG的建模，其中包括定子直接从电网以恒定的振幅和频率提供三相电压。转子还由三相电压供电，这些三相电压在稳定状态下具有不同的幅度和频率，以便达到电机的不同运行条件（速度，转矩等）。本资源在intin.m文件中给了具体的参数，可以模拟出具体的仿真结果，使用者也可以自己改变参数来模拟仿真自己的结果。(This resource is for modeling DFIG of doubly fed wind turbine, which includes the stator providing three-phase voltage directly from the grid at constant amplitude and frequency. The rotor is also powered by three-phase voltages, which have different amplitudes and frequencies in steady state to achieve different operating conditions (speed, torque, etc.) of the motor. This resource provides specific parameters in the InTin. M file, which can simulate the specific simulation results. Users can also change the parameters to simulate their own results.)
