摘　　要：为提高2D伺服阀的性能,设计应用于2D伺服阀的嵌入式电液伺服控制系统。该系统基于TMS320F2812DSP芯片设计了新型嵌入式控制器,集成A/D采样以及串口通讯等功能模块,并采用位置与电流双闭环控制算法对2D伺服阀的动静态特性进行实验测试。同时,利用图形化编程工具Lab VIEW,设计了人机交互界面,可以方便对控制器相关功能模块参数进行在线调试和实时显示工作状态。实验结果表明,该伺服控制系统工作稳定,具有良好的性能,由其控制的2D伺服阀的性能有了很大的提升。In order to improve the property of 2D serve valve, this study designs a scheme of embedded serve control system which works for 2D serve valve, this study designs a new embedded controller based on TMS320F2812, which integrates A / D sampling and serial com- munications modules ,and uses position and current of double closed loop control algorithm for static and dynamic characteristics of a 2D serve valve in research. Meanwhile, the man-machine interactive interface uses Graphical programming software LabVIEW which can be convenient for the relevant parameters of the online debugging and display the working status in real time. The experimental results show that the serve control system was stable and has good performance, and the performance of 2D serve valve has been greatly improved.
