the given file contains the implementation of the ARITHMETIC FILTER using two methods. 1.based on the mathematical concept of arithmetic mean realised using for loops. 2.using imfilt -built-in function of matlab.this function makes use of the con

This example describes how to develop speed and position control systems for a DC motor with a load. Various methods are used and the focus is on how to model and implement the various parts and not of parameter tuning. An important thing to note is

永磁同步电机比较基础的建模，没有加其他控制，大家可以一起学习，有需要的可以下载下来，自己加点控制方法(pmsm,Permanent magnet synchronous motor modeling based on comparison, without additional control, you can learn together, you need to download, add some control methods.)
