sst89c58下载器，使用keilc51的debug调试器下载。将本程序编译后写入sst89c58，并编程为remap 4kbytes。该芯片即有了keil环境下载功能,当p1.0拉低时，启动时进入下载程序，进入下载程序后将会自动删除block0,p1.0高电平时进入用户程序。 进入下载程序后，可以通过串口和keil的仿真环境连通，波特率自动调节,选择load HEX文件，即可将程序下载到sst89c58的低端32keeprom中。除了7e00-7fffh被占用-sst89c58 downloader, use the debug keilc51 Debugger download. This procedure compiled into sst89c58 and programming to remap 4kbytes. The chip has Keil environment that is the ability to download, p1.0 down, start the download entered into the download will be automatically deleted after block0, p1.0 to I enter the user program. After entering the download, through serial and Keil simulation environment connectivity, baud rate adjusts to choose load HEX documents, procedures and can be downloaded to the lower end of 32keeprom sst89c58 China. Apart from 7e00-occupied 7fffh

二阶系统的最小二乘一次完成算法辨识程序，图形的横坐标是采样时刻i, 纵坐标是输出观测值z, 图形格式为连续曲线-second-order system of least-squares algorithm for a complete identification procedures, graphics abscissa is the sampling time i, longitudinal coordinates of the output value of observation z, graphical format for continuous curve
