中文摘要：

介绍了液压促动器控制系统的集成化结构、PROFIBUS-DP通信和闭环控制策略,并对数千个样品进行闭环控制、保位和变负载随动实验。经过大量实验证明了促动器定位精度及动态性能可完全满足项目的需求,结构合理,具有良好的实用性。

英文摘要：

The integrated construction, PROFIBUS-DP communication and closed-loop control strategy of the hydraulic actuator control system were described, and thousands of samples were tested through closed-loop control, secure position and varying load follow-up examination. Extensive tests show positioning accuracy and dynamic performance of the control system meet the needs of project, it has reasonable structure and good practicability.
