Abstract:On the basis of analyzing the structure and mathematical model of multichannel signal generator,ICL8038 integrated package is used as the core. The ICL 8038 is a precision oscillating IC with a variety of waveform outputs. Simply adjusting inpidual external components can generate low-distortion sine, triangle, and square wave pulse signals from 0.001 Hz to 300 kHz. And then I designed the multichannel signal generator. The main work has been carried out in the following areas:The history, prospect, classification and characteristics of multichannel signal generator are discussed.This paper analyzes the working principle and running characteristics of 8038 integrated package, deeply analyzes and establishes the dynamic mathematical model, and studies the basic principle multi-channel signal generator, and on this basis, use the three-pole double-throw switch to achieve the 8038 signal generator output waveform control.Using the Proteus 8 Professional, the simulation of the 8038 signal generator was performed. Through simulation experiments, the feasibility of the designed control system and circuit was verified, and the knowledge of the multi-channel signal generator was further deepened.Several experiments have been carried out and the waveforms of motor speed and current of the vector control system have been obtained through experiments, and the experimental waveforms have been analyzed to a certain extent. Several experiments have been carried out and the waveforms of motor speed and current of the vector control system of PMSM have been obtained through experiments, and the experimental waveforms have been analyzed to a certain extent. The whole process and work of the experiment are summarized, and the further improvement is put forward.

课题的目的和意义
信号发生器一般被广泛用于产生频率为20Hz~200kHz的正弦信号(低频)。除了具有电压输出外,有的信号发生器还具有电源输出。因此,信号发生器具有着非常强的泛用性,在各种电子仪器设备中的低频放大器的频率特性都有着极大的用处,增益,通频带的测试或检修,它也可以当成高频信号发生器的外调制信号源来使用。另外一方面,他在校准电子电压表时,可以提供交流信号电压。低频信号发生器的原理:该系统包括输出衰减器、指示电压表等等各式各样许许多多的电子器件。信号发生器在电子产品研发过程中使用广泛,但对于电子爱好者来说,个人购买一台信号发生器来使用又显得不太合适,本次毕业设计提供一个可产生多种波形的信号发生器电路,有兴趣的电子爱好者可以自制一个,作为信号发生器来使用。
