Abstract: Online automatic monitoring and analysis of motor speed control performance is essential to evaluate，optimize and improve the performance of motor. In this paper, an online platform was established for AC motor speed control system to monitor motor speed performance，and functions of real-time acquisition, data display and identification of dynamic performance based on the waveform of response curve were realized. At last, the experiment showed that the whole platform works well to meet the need of real-time monitoring.
