摘要
根据液压伺服系统的基本理论,建立了阀控非对称缸电液位置伺服系统的数学模型,根据系统的控制目标,选取三阶工程最佳参考模型,并根据李雅普诺夫稳定性理论设计模型参考自适应控制系统,将所设计的自适应控制系统用于阀控非对称缸系统进行仿真研究,结果表明,模型参考自适应控制器能有效消除系统动态不对称特性,缩短上升时间,降低超调量,提高抗干扰能力。
Based on the basic theory of the hydraulic servo system,a mathematical model of the Asymmetric Cylinder of electro-hydraulic position servo system is established and studied.According to the control objectives of the system,this paper selects the third-order engineering best reference model,and designs the model reference adaptive control system based on Lyapunov stability theory,applys model reference adaptive control system to valve control asymmetric cylinder system and studys by simulation.
