Abstract


Synchronous drive system is an important area of the hydraulic integration technology is widely used in industrial production . Compared with other synchronous drive , hydraulic synchronous drive has many advantages of simple structure , composed of convenient, easy to control and suitable for high power applications . The synchronous drive system is the key to efficient high synchronization accuracy problems . Therefore , how to develop , develop efficient high-precision synchronous drive system engineering and technical personnel of general interest and to overcome the problem . The topic for the traditional two synchronous control modes : the valve controlled synchronous mode synchronous mode and pump control shortcomings , proposed using a combination of the volume of the pump control valve control the composite control mode to be improved , and full use of the pump control valve control each advantages maximize the improved performance of the synchronous operation of the synchronization system . Valve pump composite control system in the main valve control output guarantees dynamic performance, mainly in the homeostatic regulation of the use of double-pump control to adjust the dynamic adjustment process . The main content of the paper is as follows : 1 . Machine hydraulic servo valve control as compensation sync composite control system , and a more detailed analysis of its mathematical model . 2. Further proposed the use of electro-hydraulic proportional valve control as a composite of the auxiliary compensation system synchronization control system were calculated and analyzed . 3. The test system to simulate the actual working conditions and synchronization error line detection system , VB the Wisdows environment developed automatic data acquisition software , the synchronous system the synchronization performance evaluation under different conditions .
