Abstract
본 발명은 위치 제어기의 출력 제어 장치에 관한 것으로, 종래에는 펄스 출력의 경우 오픈-루프 콘트롤(open-loop control)방식이어서 구조는 간단하지만 에러 보상 능력이 없으며, 아날로그 전압 출력의 경우 세미-크로스-루프 콘트롤(semi-closed control)방식이어서 실제 기계 엔코더의 신호를 궤환받아 에러를 보상할 수 있으나 구조가 복잡한 문제점이 있다. 이러한 종래의 문제점을 개선하기 위하여 본 발명은 지령값 연산기와 펄스 발생기를 동시에 부가함에 의해 출력 타입에 따라 펄스 출력 타입에 따라 펄스 또는 아날로그 전압을 전동기 구동 회로에 출력함으로써 펄스 출력 타입에서의 실제 기계 오차를 보정할 수 있도록 창안한 것으로, 본 발명은 현재 위치에서의 지령값과 실제 기계 위치에 다른 보정값을 구하여 오차 보정을 수행함에 따라 펄스 또는 아날로그 전압을 출력함으로 위치 제어의 성능을 향상시킬 수 있다.The present invention relates to an output control apparatus for a position controller, and in the related art, an open-loop control method for a pulse output is simple in structure but has no error compensation capability. In the case of an analog voltage output, Since it is a semi-closed control system, the error can be compensated by receiving the feedback signal of the actual mechanical encoder, but the structure is complicated. In order to solve such a conventional problem, according to the present invention, a command value calculator and a pulse generator are simultaneously added to output a pulse or an analog voltage to the motor drive circuit according to the pulse output type according to the output type, The present invention can improve the performance of the position control by outputting a pulse or an analog voltage by performing error correction by obtaining a correction value different from the command value at the current position and the actual machine position .
