초록

In this study, we have estimated the brushless DC motor parameters by means of back-emf measurement and step input test. The validity of proposed parameter estimation method is confirmed by step res pons experiment. And the reasonable digital controller is designed with the root locus method of motor transfer function and revised Ziegler-Nichols gain determination method. The system stability is experimentally verified by the frequency domain analysis used Bode plot.
