电液位置伺服控制系统的研究

以某公司的电液位置伺服控制系统为对象,分析了该伺服系统的液压动力元件、液压执行元件、主控制器等构成的反馈控制系统工作原理。根据系统的控制要求,完成了液压部分各个模块的性能分析,并提出以FPGA为核心的控制器方案。通过对系统实际性能要求分析,给出了系统总体设计方案,并且进行了现场调试,实现数据的实时交互,并将处理结果以曲线的形式展示,以供数据分析处理并进行参数调整。结果证明,该控制器能够满足控制系统提出的总体任务要求,达到了预期的设计效果。

Electro-hydraulic Position Servo Control System

Taking a hydraulic servo control system of a company as the object, we analyze working principle of a feedback control system composed of hydraulic power components, hydraulic actuators, and main controllers of the servo system. According to control requirements of the system, the performance analysis of each module of hydraulic part is completed, and a controller scheme based on the FPGA is proposed. Through the analysis of actual performance requirements of the system, we give an overall design of the system, and carry out an on-site commissioning work to achieve real-time data interaction, and display the processing results in the form of curves for data analysis and parameter adjustment. The results show that the controller can meet the overall mission requirements of control system and achieve the desired design results.
