电机拖动里的用空载点和负载点做出直流电机的固有机械特性曲线(failed to translate)

this is matlab program for pi/4 qpsk modulation

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

这是三组程序，分别计算hibert变换，小波时频分布，wigner-vill分布，并且画出谱图(This is three groups of program, calculate hibert transform, wavelet time-frequency distribution, wigner- vill distribution, and draw the spectrogram)
