电液比例泵控马达系统辨识及实验分析研究

摘要

With the rapid development of electro-hydraulic proportional control technology applications and pump motor control system, hy-draulic system in order to make the production process to meet the higher demands on system performance, the need to improve the re-sponse characteristics of the hydraulic system and reliability, and the establishment of the system accurate model is the foundation to further improve and perfect the system design. Chang'an University using electro-hydraulic proportional pressure-flow control experiment bench resulting experimental data, combined with Matlab software, using ARMAX model identification method for electro-hydraulic proportional pump controlled motor system conducted experiments to identify, and the system has been applied to the control strategy simulation.%随着电液比例控制技术和泵控马达系统的应用的迅速发展，为了使液压系统能够满足生产过程对系统性能的更高要求，必须提高液压系统的响应特性及工作可靠性，而建立系统的精确模型则是进一步改进和完善系统设计的基础。利用长安大学电液比例压力——流量控制实验台上进行的所得实验数据、结合Matlab软件、运用ARMAX模型辨识方法对电液比例泵控马达系统进行了实验辨识，并对系统施加控制策略进行了仿真分析。
