11. VMD-Parameter-Estimation

  变分模态分解在信号分解精度和噪声鲁棒性方面具有明显优势,但需预先确定模态数K,而目前K 只能靠先验知识进行预估,如果预估的K 与实际信号存在差异,会导致分解误差较大。针对以上问题,利用EMD 不需预先设定模态数的自适应分解特点,通过对EMD 分解结果的分析,进行VMD 分解模态数的估计,并通过仿真信号分析及滚动轴承故障信息提取(Variational modal decomposition has obvious advantages in signal decomposition accuracy and noise robustness, but it is necessary to determine the modal number K in advance. At present, K can only be predicted by a priori knowledge. If the estimated K exists with the actual signal Differences, will lead to greater decomposition error. In order to solve the above problems, EMD is used to analyze the decomposition results of EMD without pre-setting the adaptive decomposition of modal number. The estimation of VMD decomposition mode is carried out and analyzed by simulation signal and rolling bearing fault information extraction)

  针对滚动轴承早期故障特征提取困难的问题,提出一种基于参数优化变分模态分解的轴承早期故障诊断方法。首先利用粒子群优化算法对变分模态分解算法的最佳影响参数组合进行搜索,搜索结束后根据所得结果设定变分模态分解算法的惩罚参数和分量个数,并利用参数优化变分模态分解算法对故障信号进行处理。(Aiming at the difficult problem of early fault feature extraction of rolling bearing, an early fault diagnosis method based on parameter optimization variational modal decomposition is proposed. Firstly, the particle swarm optimization algorithm is used to search the parameters of the variational modal decomposition algorithm. After the search, the penalty parameters and the number of components of the variational modal decomposition algorithm are set according to the obtained results. The modal decomposition algorithm handles the fault signal.)

  32位基于ARM微控制器STM32F101xx与STM32F103xx的固件函数库。该函数库是一个固件函数包, 它由程序、数据结构和宏组成,包括了微控制器所有外设的性能特征。该函数库还包括每一个外设的驱动 描述和应用实例。通过使用本固件函数库,无需深入掌握细节,用户也可以轻松应用每一个外设。因此, 使用本固态函数库可以大大减少用户的程序编写时间,进而降低开发成本。 为了节省开发时间和工作效 率,所以一般我们进行应用程序编写的过程中都会去使用芯片厂商提供的固件库像Nuvoton和TI都为他们 的32位产品制作了固件库,不过他们对固件库的称呼是库函数,其实实质都是一样的,里面大量采用结构 体,枚举和指针,能够比较方便快捷的帮助用户上手芯片,当然你觉得库函数没有达到你的要求你也可以 进行一定的修改,不过对于基本的应用库函数还是能够满足普通用户的需求的。这里我将记录我在MDK 环境下移植STM32F103xx系列的固件库的过程,其他产品线的固件库也基本都一样。(32-bit firmware library based on ARM microcontrollers STM32F101xx and STM32F103xx. The library is a firmware function package, It consists of programs, data structures, and macros that include the performance characteristics of all peripherals of the microcontroller. The library also includes drivers for each peripheral Description and application examples. By using this firmware library, users can easily apply each of the peripherals without having to master the details. therefore, The use of this solid-state library can greatly reduce the user s program preparation time, thereby reducing development costs. In order to save development time and work efficiency Rate, so we generally use the process of writing the application will be used to provide the chip vendor firmware library Nuvoton and TI are for them 32-bit products produced a firmware library, but they are called on the firmware library library function, in fact, are the same substance, which a large number of structures )
