泵控容积调速系统的实时控制研究

Study of real-time control in pump-controlled positive-displace-ment speed regulating system

本文在分析液压泵控容积调速系统特性的基础上,提出以单片机MCS—51为控制单元,以步进电机为执行元件的闭环实时控制系统的方案,介绍了系统实时控制的实现方法和系统实际运行的实验结果。

This paper puts forward the layout of closed loop real-time control system taking MCS-51 single chip microcomputer as control element an a step motor as the actuator, and introduces implementation method of real-time control of the system and experimental result of actual operation of the system.
