摘要
本文分析了水压液压缸在同步控制中的应用。在小闭环内采用PID控制 ,大环内采用并、串复合的同步控制方法实现水压双缸同步控制。通过对比例阀和水压缸进行数学建模 ,用MATLAB软件作了理论动态仿真 ,实现对双缸的高精度同步控制。并将仿真结果与实验结果进行对比和分析 。
The application of water hydraulic parallel cylinders in synchronization control was analyzed.Synchronization control was realized through the PID in inner closed loop and the series-parallel connection in outer loop.The mathematic models of proportional valve and water hydraulic cylinder were given,through the imitation of dynamic software of MATLAB,the high-precise synchronization control of the water hydraulic parallel cylinders was succeeded.And through the compare of the results of the imitation and experiment,the feasibility of the application of the synchronization control of water hydraulic parallel cylinders was proved and the problems which lie now were presented.
