交流电动机的矢量控制（Transvector Contrl）理论，从理论上解决了交流电动机转矩的高性能控制问题。其基本思想是在普通的三相交流电动机上设法模拟直流电动机转矩控制的规律，在磁场定向坐标上，将电流矢量分解成产生磁通的励磁电流分量 和产生转矩的转矩电流分量 ，并使两分量互相垂直，彼此独立，然后分别进行调节。这样，交流电动机的转矩控制，从原理和特性上就与直流电动机相似了。因此，矢量控制的关键仍是对电流矢量的幅值和空间位置的控制。(AC motor vector control (Transvector Contrl) theory, control theory to solve the problem of high-performance AC motor torque. The basic idea is to try to simulate the DC motor torque control law in the ordinary three-phase AC electric motor in field-oriented coordinates, the current vector decomposed to produce the excitation current component of the magnetic flux generating a torque current component and torque, and two components perpendicular to each other, independently of each other, and then were adjusted. Thus, AC motor torque control, the principle and characteristics of the DC motor on and similar. Therefore, the key vector control is still the amplitude and spatial position of the current vector control.)

1、修复0xfd Bug：是通过替换C51.exe和CX51.exe实现的，本补丁所提供的C51.exe和CX51.exe是使用原版的文件修改制作。对于其准确性，不做任何保证。2、添加STC单片机列表：是通过替换UV4.cdb文件和添加STC头文件实现的，本补丁所提供的UV4.cdb是根据STC官方公布的UV3.cdb文件制作。其准确性不做任何保证。3、STC的头文件（支持鼠标右键插入头文件）：头文件是从STC官网下载的，未作任何更改。头文件中虽然有STC12C54XX系列单片机的头文件4、运行程序后点击“安装程序”即可，详细说明点击“了解详情”进行查看(A repair 0xfd Bug: by replacing C51.exe and CX51.exe achieve, the patch provided C51.exe and CX51.exe is to use the original file to modify production. For its accuracy, without any guarantees. 2, add STC SCM list: Yes, and add files by replacing UV4.cdb STC header files to achieve, this patch is provided UV4.cdb UV3.cdb under STC official document production. Its accuracy is not guaranteed. 3, STC header files (support right into the header file): header files are downloaded from the official website of STC, did not make any changes. Although there STC12C54XX header file MCU header files 4, run the program and click the " Setup" button, a detailed description click on the " learn more" to view it)
