代码说明:

  电子爱好者们经常希望测试自己的音频设备如声卡、碟机、功放、音箱等的性能指标,却苦于没有价格高昂的专业测试设备而无从下手,设计制作时也无法进行必要的测试指导。有些CD碟提供了测试信号,如著名的“雨果发烧碟(一)”、“My Disk”等,《无线电》也曾推出音频测试CD。但CD信号的精度有限,而且没有操作系统的配合,测量、记录和分析都很不方便。(Electronic fans often want to test their audio devices such as sound cards, CD, amplifier, speakers and other performance indicators, but have no specialized test equipment without the high price the start, can not carry out the necessary tests to guide the design of production. Some CD discs provide a test signal, such as the famous Hugo Audiophile CD (a) , My Disk and so on, Radio has launched an audio test CD. CD signal but the accuracy is limited, and there is no tie, measurement, recording and analysis of the operating system is very inconvenient.)

    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.)
