DC motor equips the advantages of precise transmission ratio classification, wide speed type spectral, compact motor structure and overload bearing. The research of accurate speed and position control of DC motor has always been the experimenting focus. In order to explore an efficient and flexible method of DC motor control, in this paper, a positon control system has been established for PMDC Motor based on LabVIEW by NI Company. The established position control system uses NI-DAQmx, ADC function, PID toolkit and PWM module in LabVIEW coupled with the using of NI USB-6210 to achieve accurate control purpose. The validity of established position control system is verified by experiment.
