摘要
为了满足电液伺服作动器控制精度及运行安全的需要,提出了基于CRIO架构的电液伺服作动器控制系统,该系统能够实现信号采集、故障报警、过载保护和双缸同步控制等功能。以伺服油缸双缸同步为研究对象,介绍了作动器液压工作原理及LabVIEW测控系统的总体设计方案,提出了积分分离PID算法的双缸同步控制策略,建立电液伺服作动器实物平台,经试验其运行效果良好,单缸伺服控制误差在±2 mm范围内,双缸同步控制误差在±4 mm范围内,满足工程机械底盘悬架、车桥结构应力、疲劳性能等测试需求。
In order to meet the needs of control accuracy and operational safety of electro-hydraulic servo actuators,a control system for electro-hydraulic servo actuators based on CRIO architecture is proposed.This system can achieve functions such as signal acquisition,fault alarm,overload protection,and dual cylinder synchronous control.Taking servo cylinder dual cylinder synchronization as the research object,the hydraulic working principle of the actuator and the overall design scheme of the LabVIEW measurement and control system are introduced.A dual cylinder synchronization control strategy based on integral separation PID algorithm is proposed,and an electro-hydraulic servo actuator physical platform is established.After testing,the operation effect is good,with a single cylinder servo control error within±2 mm and a dual cylinder synchronization control error within±4 mm,meeting the requirements of engineering machinery chassis suspension Test requirements for stress and fatigue performance of axle structures.
