its about svpwm dtc of an induction motor drive

matlabfir 是一个用MATLAB设计FIR的程序，自己编的，如果有不当之处，希望斑竹帮忙看看(MATLAB importan easy)

说明：  三维立体分布图 砷元素的 2011 国赛数模(3—D litifenbu )

说明：  模型预测电流控制其控制思想基于以下原理：首先，功率变换器产生的开关状态个数有限，且通过建立模型可以预测每一个开关状态下被控变量的对应变化特性；其次，定义价值函数评价被控变量的预测值，为判别最优有限开关状态提供依据；最后，计算出每一种开关状态下的价值函数值，以此评价每一种开关状态下被控变量预测值的优劣，选择出最优的开关状态并应用。(The control idea of model predictive current control is based on the following principles: firstly, the number of switching states produced by power converter is limited, and the strain characteristics of controlled variables under each switching state can be predicted by establishing a model; secondly, the value function is defined to evaluate the predicted values of controlled variables, which provides a basis for judging the optimal finite switching state; lastly, the optimal finite switching state is calculated. The value function value under switching state is used to evaluate the predicted value of controlled variables under each switching state, and the optimal switching state is selected and applied.)

说明：  function [ret,x0,str,ts,xts]=s3(t,x,u,flag) s3 is the M-file description of the SIMULINK system named s3. The block-diagram can be displayed by typing: s3. SYS=s3(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

matlab处理地震资料的有关比较简单的成程序，segy文件的读取程序及输出segy格式的程序，另外还有雷克子波的程序等(matlab processing seismic data into a relatively simple procedure, segy file read program output segy formats procedures, in addition Leike Zi wave program)

这是应用ｍａｔｌａｂ模拟电容充放电的过程，编写一段程序，希望对大家有用。(This is the application matlab analog capacitor charging and discharging process, the preparation of a program, in the hope that useful. )

Matlab 写的kmeans slc 算法 还包括实验报告，其中有实验结果图的对比(Matlab kmeans and slc algrithms, reports with experimental results attached I hope it is useful for you )

说明：  一个matlab程序，m序列产生程序, 因为M序列很重要,要的可以下哦 (a procedure for selecting the sequence of m, because the M series is very important, to be the next Oh)
