工具箱，控制理论发展的最新成果，很好的东西，分分享(Toolbox, the latest development of control theory, very good, sub-share)

小波阈值去噪，小波变换是一种信号的时间——尺度（时间——频率）分析方法，它具有多分辨分析的特点，而且在时频两域都具有表征信号局部特征的能力(Wavelet threshold denoising)

说明：  基本的粒子滤波算法，所用数值模型为带控制量的非线性模型，可修改噪声类型，并可和EKF相比较(Basic particle filter algorithm for the numerical model used to control the volume with the non-linear model, can modify the type of noise can be compared and the EKF)

this code is used to determine the parameters of johnson distribution for its bounded distribution .

说明：  矢量控制是目前交流电机的先进控制方式，一般将含有矢量变换的交流电机控制都称 之为矢量控制，实际上只有建立在等效直流机模型上，并按转子磁场准确定向的控制，电机才能获得最优的动态性能。 矢量控制的基本思路是以产生相同的旋转磁动势为准则，将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流，分别加以控制，以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance. The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)
