： 讨论了一种采用 D S P芯片T MS 3 2 0 L F 2 4 0 7实现无传感器永磁同步电机转子磁场定向矢量控制的方案， 介 绍了永磁同步电机的数学模型和矢量控制的基本原理， 给出了在无位置传感器的情况下电机转子位置信号的确定 方法， 采用i ， = 0的对凸极式转子磁路结构的无传感器永磁同步电动机的控制方法， 说明采用高速数字信号处理器 易于实现复杂的矢量控制算法， 可以有效地解决电机的强耦合特性．(： A s o l u t i o n t o c o n t r o l a p e r ma n e n t ma g n e t s y n c h r o n o u s m o t o r ( P MS M)o f s e n s o r l e s s u s i n g t h e TM$ 3 2 0LF 2 40 7 i S d i s c u s s e d． A br i e f i n t r o d u c t i o n o f t h e ma t h e ma t i c mo d e l a n d t he v e c t o r c o n t r o l o f PMS M i s p r e s e n t e d，a n d t h e me t h o d o f a s c e r t a i n i n g t h e r o t o r p o s i t i o n u nd e r t h e c i r c u ms t a n c e o f s p e e d s e n s o r l e s s i s a l s o me n t i o n e d．Th e c o n t r o l me t h o d o f i d 0 o n s a l i e n t p o l e PMSM wh i c h i s s e n s or l e s s i s p ut f o r wa r d，wh i c h s h o ws t h a t i f we us e t h e d i g i t a l s i g n a l p r o c e s s o r we c a n ma k e t h e c o mpl i c a t e d v e c t o r c o n— t r o l a r i t h me t i c c o me t r u e e a s i l y，a n)

Program to use your camera as a scanner. Automatically detects the page on the picture. (Description Useful program if you don t have a scanner or need to scan quickly a lot of pages. It detects the page on the picture, make it rectangular, cut the borders and enhance the contrast. Function parameters are the input picture filename and output filename. Some parameters that can be changed are described in the function. Be careful with the flash of the camera, it creates a non-homogeneous luminosity difficult to clean. Required Products Image Processing Toolbox MATLAB release MATLAB 7.5 (R2007b) )

说明：  这是一个计算盒子维数的程序，值得我们收藏(This is a procedure for calculating the box dimension, it is worth our collection)

实现图像压缩，运用小波处理技术， matlab实现，你懂的(using wavelet to compress the image by matlab )

北邮一个老师的讲义，还有作业和实验，是学习matlab和数学建模的辅导材料(Beijing University of Posts and Telecommunications a teacher' s lecture notes, there are operations and experiments, and mathematical modeling to learn matlab counseling materials)

GAUSS滤波器 MATLAB语言 本科毕业设计需要(GAUSS filter)

实现随机信号序列的QPSK调制和相干解调，观察信号的星座图，计算误比特率和误码率。(this code is designed for the signal s QPSK modulation and demodulation exactly. Meanwhile, the BER and SER were estimated and drawed.)

说明：  在求解装备的资源约束型装配线一类平衡问题时，借助遗传算法和粒子群算法，并对遗传算法和粒子群算法进行改进，利用matlab程序进行优化求解。(The type 1 assembling line balancing problem for certain equipment is sovled with modified genetic-particle swarm optimization algorithm by using matlab languge.)
