摘　　要：为了实现对三相永磁式同步交流伺服电机频域响应的检测需求,提出了一种基于ARM单片机的变频率PWM正弦信号发生器的设计方案,并完成系统的软硬件设计。该系统的硬件部分采用STM32F103系列ARM单片机,用于PWM方式输出变频率的模拟正弦信号,软件部分采用Keil进行编程。通过软件仿真和示波器对输出信号进行检测,利用该方案的正弦信号发生器对三相永磁式同步交流伺服电机进行频率响应测试,将得到的数据利用matlab绘图,实验结果表明此方案产生的正弦信号发生器满足电机频响需求。In order to satisfy the requirement of frequency domain response of AC servo motor, we proposed a method for produce a sine-wave signal of frequency conversion based on ARM. The hardware system is used to PWM output to produce a sine-wave signal of frequency conversion by STM32FI03. The software system adopts the Keil as development environment. Simulations using software and oscilloscope accomplish to detect output signal. The results show that the proposal can satisfy the requirement of frequency domain response of AC servo motor.
