語音信號是基於時間軸上的一維數位信號,在這裏主要是對語音信號進行頻域上的分析。在信號分析中,頻域往往包含了更多的資訊。對於頻域來說,大概有8種波形可以讓我們分析:矩形方波,鋸齒波,梯形波,臨界阻尼指數脈衝波形,三角波,餘旋波,余旋平方波,高斯波。對於各種波形,我們都可以用一種方法來分析,就是傅立葉變換:將時域的波形轉化到頻域來分析。(Voice signal is based on the timeline of one-dimensional digital signal, where mainly the speech signal in frequency domain analysis. In signal analysis, frequency domain often contains more information. For the frequency domain for about 8 allows us to analyze waveforms: rectangular square wave, sawtooth, trapezoidal wave, the critical damping index pulse, triangle wave, I spin wave, I spin square wave, Gaussian. For all waveforms, we can analyze in a way that is Fourier transform: the transformation of time domain waveform into the frequency domain to analyze)

异步电机的双闭环控制
说明: 矢量控制是目前交流电机的先进控制方式,一般将含有矢量变换的交流电机控制都称 之为矢量控制,实际上只有建立在等效直流机模型上,并按转子磁场准确定向的控制,电机才能获得最优的动态性能。
矢量控制的基本思路是以产生相同的旋转磁动势为准则,将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流,分别加以控制,以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance.
The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)
