摘　　要：针对大型液压机等液压系统的多液压缸同步运动问题,提出了使用HNC实现精确同步控制的解决方案。阐述了液压实验台控制原理以及系统硬件、软件构成。该系统实现液压实验平台的正常运行,分析了实验所得数据。实验结果表明HNC在液压控制系统中应用精度很高。Aiming at the problem of multi-cylinder synchronous motion of hydraulic system of large hydraulic machines, a solution to achieve the precision synchronous control by using a hydraulic numerical controller （ HNC） was put forward. The control principle, system hardware and software structure of the hydraulic test platform were elaborated. The normal operation of the hydraulic test plat-form was realized by this system, and the tested data was analyzed. The test results indicate that the application of HNC in the hydraulic control system has very high precision.
