| 摘 要： | 为提高阀控单出杆缸电液伺服系统性能,在构建阀控单出杆缸电液伺服系统动态机理模型基础上,提出了一种具有加速度前馈的二阶线性自抗扰控制(Linear Active Disturbance Rejection Control, LADRC)方法,采用奇异摄动理论分析了闭环系统稳定性,并针对系统响应性能和抗干扰性能与传统PID控制进行仿真和实验对比。结果表明:具有加速度前馈的LADRC对系统中存在的多源不确定扰动具有较强鲁棒性,能有效提高系统动、静态性能,并实现对给定信号的快速、精确轨迹跟踪。

| Abstract: | In order to improve the performance of the valve-controlled single-rod cylinders electro-hydraulic servo system, on the construction of the dynamic mechanism model of the system, the second-order linear active disturbance rejection control with acceleration feed-forward is proposed. The system stability is analyzed based on the singular perturbation theory. And the response and anti-interference performance are compared by simulation and experiment, with traditional PID control. The results show that the proposed control strategy has strong robustness to the multi-source uncertain disturbance in the system, can effectively improve the dynamic and static performance of the system, and achieve the fast and accurate tracking for the given signal. |
