Automation of the Parameter Measurement of D.C. Servomotors Using a Microcomputer

마이크로 컴퓨터를 이용한 직류 서어보전동기의 파라미터 측정의 자동화

This paper describes the efforts to develop an PC based parameter identification system for the D.C. servomotor. The whole identification process of signal generation, measuring, parameter determination is fully automated. To minimize errors due to the ripple component in the measured armature current, digital averaging filter is employed. The proposed parameter correction method using the deadzone current and the time to reach the peak current resulted in excellent agreement between the measured current and estimated current using the model.
