基于stm8l15x系列单片机移植的bmp180气压海拔传感去驱动程序模拟IIC，实际用stm8l152K4T6单片机，串口打印数据，亲测可用。( Bmp180 pressure altitude sensor stm8l15x MCU-based portable driver to simulate IIC, the actual use of stm8l152K4T6 microcontroller, serial print data, pro-test available.)

这是一个用51单片机系统仿真ucosii工作的protues电路 本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统 使用方法： 1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹 中的extern ram.DSN 文件 2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项 中选择yy.hex文件。 (yy.hex其实就是yy文件夹中keil文档编译出来的hex文 件，yy文件夹是杨屹的ucos51 系统，用keil 2 可以打开) 3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率) 4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率 5.保存，点击运行就可以看到经典的hello world 了。 (1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation The extern ram.DSN file 2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file. (yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2 Can open) 3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency) 4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options 5. Save, click Run you can see the classic hello world)

针对感应电机矢量控制系统，提出了一种可以同时补 偿死区误差电压并消除零电流钳位现象的死区补偿方法。在分析影响死区效应的因素以及等效死区时间表达式的基础上，采用平均死区时间补偿法，在两相静止轴系中对等效死区时间产生的误差电压进行了补偿。为了提高电流极性检测的准确性，利用旋转轴系中的励磁电流和转矩电流分量经过 坐标反变换，判断电流在两相静止轴系所处的扇区来决定需 要施加的补偿电压。(A dead—time compensation strategy is presented to compensate dead time elTor voltage and eliminate zero·- current clamping effect for vector controlled induction motor drive system．The factors influencing dead·time effect are analyzed,and expression of equivalent dead time is deduced.Average dead·time compensation technique is adopted to compensate error voltage at two—axes stationary frame．To improve accuracy of current polarity detection，components of magnetizing current and torque current are transformed into two-axes stationary frame．Therefore，compensating voltage vector Can be determined according to the sector where the current vector locates．)
