专利汇可以提供Position control system of numerical control machine tool专利检索,专利查询,专利分析的服务。并且PURPOSE: To eliminate offset without unstabilization of a closed loop to perform the position control of a numerical control machine tool accurately by providing an integrating element and a means, which compensates unstabilization of the closed loop caused by this element, in the closed loop.
CONSTITUTION: In the numerical control machine tool of the semi-closed loop system, only an integration characteristic is given to gain setting equipment GC1, and compensating equipment CPS formed with the operation function of a processor is provided in the preceding stage of gain setting equipment GC1 for the purpose of stabilizing the closed loop. By this constitution, offset can be eliminated without unstabilization of the closed loop, and consequently, a high-precision position control can be performed. Further, since adjustment to stabilize the closed loop is performed by the processor, no complicated adjustment is required.
