qsmx-PWMfreq
- 而电机控制的PWM 模式讨论似乎针对第二类的较多。因为PWM 控制对于遥控模型的 重要程度较高。而遥控玩具一般不调速，H 桥只是为了换向。工业控制由于减速后转速已很 低，不再迫切需要调速了，直接用通断控制已能满足大多数的要求。-And motor control of the PWM mode of the discussion seems more for the second category. PWM control as an important model for the re

- 将高阶时频表示引入机械故障诊断领域。介绍了Wigner 高阶矩谱(WHOS)的概念、定义。针对多分量信号Wigner 高阶矩谱的交叉项会产生“虚假信号”,结合局域波法, 提出了一种抑制WHOS交叉项的新方法。首先对复杂信号进行预处理, 利用局域波分解方法把其分解成有限个具有单分量特性的基本模式分量,然后对每个基本模式分量计算WHOS。该方法能有效抑制WHOS时频分布的交叉项。通过仿真实验和转子的故障实验,以Wigner 双谱为例, 验证了该方法的实用性,为故障诊断的特征提取提供了新的工具-Hig
