利用PSO粒子群搜索算法,辨识PID参数:Kp,Ki,Kd.结果表明虽然该方法辨识精度不是很高,但是也有一定可信度.(Use english PSO Particle Swarm algorithm, identification of PID parameters: Kp, Ki, Kd. The results show that although the method is not very high recognition accuracy, but it also has a certain credibility.)

说明：  二维傅立叶变换的Matlab实现，是利用图像处理软件对给出的图像进行傅立叶变换处理。在Matlab中，函数fft2表示二维傅立叶变换，函数ifft2则表示二维傅立叶反变换。(The Fourier transform of the image)

说明：  这是一条跟踪航迹，通过航迹起始，数据关联，目标跟踪形成的航迹，供目标跟踪初学者使用(This is a tracking track, through the track start, data association, target tracking formed track, for target tracking beginners use)

LCD1602的数据写入及CGRAM的使用 编程 2010-06-19 17:41:11 阅读84 评论0 字号：大中小 订阅 1.当使能端E由1变为0时，执行写指令，数据被写入。 例如，欲写入数据i到DDRAM： void WDR(uchar i) { CheckBusy();//检忙 LCD_RS=1; LCD_RW=0; LCD_EN=0; Delay(); LCD_DATA=i;//数据输出到定义端口 Delay(); LCD_EN=1; Delay(); LCD_EN=0;//这一步才开始写入到LCD Delay(); } 2.CGRAM 1602能存储8个自定义字符，这8个自定义字符存储空间的首地址分别是：0X40,0X48,0X50,0X58,0X60,0X68,0X70,0X78。 以0x40来说，它的存储空间如图所示：(riting of LCD1602 and the Use of CGRAM)
