| Abstract: | A high accurate position servo control technique using double closed-loop is studied and the new position control system with double closed-loop of rotating and linear displacements for precision NC machine tools has been developed. The important features of the system are:it possesses not only the control precision of the fully closed-loop systems,but also the stability of the open loop systems. Besides, it has a wide applicable domain and can implement the closed-loop control with high accuracy, high stability, and excellent dynamic performance for variant NC machine tools. This system has been used on tens of NC machine tools and very good results have been obtained in the machining of complex mould parts and housing parts with precision holes. |
