摘要:

 为了解决闭式泵控系统液压缸流量不匹配问题并提升液压系统的能量效率,设计了一种变排量、变转速的非对称泵控液压系统控制方案。通过综合控制两个自由度来达到调控排量,实现了液压缸伸缩位置与运动速度的控制功能。此时控制转速和控制排量发生叠加,从而获得了更快的系统响应速度。最后,分别从速度开环、闭环控制方案,以及负载特性等方面对非对称泵控液压系统控制方案及其回路特性展开了仿真分析。研究结果表明:速度开环控制回路系统形成了不对称的速度,速度闭环控制回路系统则表现出更稳定的状态,其可以达到更高的位置控制精度,达到平稳运行状态,获得更优位置控制性能;闭环速度可以保持稳定状态,基本不受负载的影响。

 In order to solve the problem of hydraulic cylinder flow mismatch in closed pump control system and improve the energy efficiency of hydraulic system, a control method of asymmetric pump-controlled hydraulic system with variable displacement and variable rotation speed was designed. Then, through the comprehensive control of two degrees of freedom, the displacement was adjusted, and the control function of telescopic position and movement speed of the hydraulic cylinder was realized. Meanwhile, the control speed and control displacement were overlapped to obtain a faster system response speed. Furthermore, the control scheme and loop characteristics of the asymmetric pump-controlled hydraulic system were simulated and analyzed respectively from the aspects of speed open-loop and closed-loop control schemes and load characteristics. The results show that an asymmetrical speed was formed in the speed open-loop control system, while the speed closed-loop control system exhibits a more stable state to achieve higher position control accuracy and a stable operation state which could obtain better position control performance. The closed-loop speed could keep stable state and is basically not affected by the load.
