摘　　要：本文设计了一种基于FPGA的电机测试系统,融合了STM32实时控制、Qt上位机人机交互界面、电机转速转矩的实时测量。STM32接收上位机指令并采用FSMC总线对FPGA进行控制和数据流不间断传输。实验结果表明,该电机测试系统的正弦波输入信号AI测量频率范围为5-300Hz,幅度范围为-7V到7V,幅度的测量精度为1%-3%。方波输入信号CI的频率范围为1-100KHz,频率的测量精度为0.2%。直流偏置信号DO稳定输出3.35-3.48V电压。方波输出CO频率范围1-100KHz。正弦波AO输出峰峰值可达10V,频率输出的相对误差小于0.2%。This paper designs an FPGA-based motor test system,which combines STM32 real-time control,Qt upper computer human-computer interaction interface,and real-time measurement of motor speed and torque.STM32 receives instructions from the host computer and uses the FSMC bus to control the FPGA and transmit uninterrupted data flow.The experimental results show that the measurement frequency range of the sine wave input signal AI of the motor test system is 5−300 Hz,the amplitude range is−7V to 7V,and the amplitude measurement accuracy is 1%−3%.The frequency range of the square wave input signal CI is 1-100KHz,and the frequency measurement accuracy is 0.2%.The DC bias signal DO outputs a voltage of 3.35−3.48V stably.The CO frequency range of square wave output is 1−100KHz.The peak-to-peak value of sine wave AO output can reach 10V,and the relative error of frequency output is less than 0.2%.
