摘　　要：由于阀控伺服作动系统存在的非线性因素,传统的建模方法所建立的数学模型无法准确地反映系统实际情况。为提升液压系统的控制精度及动态响应性能,解决在实际系统试验中出现的动态特性超差问题,对可能引起的因素及关键参数进行研究,重点分析引起系统静态误差的主要因素,同时分析系统各关键元件的固有频率和阻尼比对系统动态性能的影响。利用Matlab/Simulink软件对系统进行非线性建模,理论推导计算及仿真结果分析表明,较高的系统各关键元件固有频率和阻尼比有利于提高系统动态性能。Due to the nonlinear factors in the valve controlled servo actuator system,the mathematical model established by traditional modeling methods cannot accurately reflect the actual situation of the system.In order to improve the control accuracy and dynamic response performance of the hydraulic system,and solve the problem of dynamic characteristics exceeding the tolerance in actual system tests,the possible factors and key parameters that may be caused are studied,with a focus on analyzing the main factors that cause static errors in the system.The influence of natural frequencies and damping ratios of key components on the dynamic performance of the system is analyzed.The nonlinear modeling of the system is carried out by means of MATLAB/Simulink software.The theoretical derivation calculation and simulation result analysis show that higher natural frequencies and damping ratios of key components in the system are beneficial for improving the dynamic performance of the system.
