Dead-time-Compensation-
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．)

多机通信，设计了一种基于MCS－51系列单片机AT89S52 的多机通信系统。当1号机与2号机通信时，1号单片机为主机，2号机为从机。主机通过串口向从单片机发送指定格式的数据，从单片机收数据并作出响应，从机通过LED数码管显示通信状态。1号单片机通过矩阵键盘控制通信过程与显示。这通信模式是主从模式，只能是主机发信息给从机。当1号机与3号机通信时，不存在主从机之分，是平权模式。1号机可以通过按键发信息给3号机，3号机也可以通过按键发信息给1号机，通过各自的数码管显示通信数据，LED灯显示通信状态。(Multi-machine communication, design a multi-machine communication system based on MCS-51 series single-chip AT89S52' s. When the 1st and the 2nd machine-machine communication, the 1st microcontroller host, the 2nd machine as a slave. Data sent to the host computer through the serial port specified format from SCM, SCM and respond to the received data from the slave via LED digital display communication status. 1 MCU control the communication process through the matrix keyboard and display. This mode of communication is a master-slave mode, the host can only send a message to the slave. When the 1st and the 3rd machine-machine communication, there is no slave master points, is affirmative mode. The 1st machine can send a message to the 3rd through the key machine, the 3rd machine can also send information via the button to the 1st machine, display data communication through their digital tube, LED lights display the communication status.)
