基于ITAE准则的大流量平衡阀关键参数优化研究
|
摘要
在Simulink中建立大流量双反馈平衡阀的动态特性仿真模型,将误差积分准则ITAE作为综合性能指标,结合Simulink建模仿真和MATLAB的优化函数对平衡阀的动态性能反复交替进行仿真和优化,最终获得使负载控制阀动态性能最优的参数组合。该方法为液压阀综合动态性能提供了明确量化的优化目标,克服了传统试凑法寻优的缺点,对于液压阀类元件结构参数优化具有普遍的借鉴意义。
A dynamic model of a large flow double feedback load control valve is established by means of Simulink, and the dynamic characteristics of the valve are repeatedly simulated and optimized based on the ITAE criterion by use of modeling simulation of Simulink and optimization functions of MATLAB. Finally, a parameter combination that optimizes its dynamic characteristics is found. The proposed method can provide an explicit quantitative target for optimizing the comprehensive dynamic performance of the valve, and overcome defects of traditional design and optimization by trial and error, and it can also serve as a reference for optimization of structural parameters for other kinds of hydraulic valves.
