Abstract

본 발명은 마이콤의 연산과정에서 발생되는 버림오차를 없애 연산의 정확성을 확보하는 방법에 관한 것으로, 일반적인 소프트웨어의 서보제어방법에 있어서는 마이콤의 연산과정에서 발생하는 버림오차를 무시하여 다시한번 동일 루틴의 연산을 행할때 이전의 오차가 자동적으로 무시되어 정확한 연산이 불가능하게 되는데, 이를 해결하기 위하여 본 발명은 마이콤의 연산과정에서 발생되는 버림오차값을 저장하였다가 다음의 샘플링 타임시 즉, 다시 한번 같은 루틴의 연산을 반복하게 될때, 이전에 저장해 놓았던 오차를 더하여 현재의 제어에 반영시키므로써 정확한 제어를 실현할 수 있게하였다.The present invention relates to a method for securing the accuracy of operation by eliminating the throwing error generated during the operation of the microcomputer. In the servo control method of general software, the same routine is ignored once again by ignoring the throwing error generated during the microcomputer operation. When the calculation is performed, the previous error is automatically ignored, so that accurate calculation is impossible. To solve this problem, the present invention stores the truncation error value generated during the calculation process of the microcomputer, When the routine's operation is repeated, the previously stored error is added to the current control to realize accurate control.
