摘要
利用LabVIEW进行虚拟仪器开发,设计一种"软"信号发生器。此信号发生器可以方便输出正弦波、方波和指数波等各种不同波形的信号,输出信号的频率和幅值等参数可通过前面板控制。用这种信号发生器作为超声波电机的信号源产生所需的信号来研究超声波电机的特性。在此基础上构建了基于虚拟仪器的超声波电机控制系统。实验表明,这种信号源效果良好且方便。
By use of LabVIEW software, a new kind Different signals such as sine waveform, step waveform of signal generator based on virtual instrument is designed. and exponential waveform are available. Its frequency and phase can be adjusted precisely through the front panel. For studying the characteristic of USM, the controlling system of ultrasonic motor is established. The experiment of speed control of USM is carried out whose input signals are generated by the signal generator. It shows that the signal generator is convenient and effective through experiments.
