本文分析了电液伺服试验机的工作状态以及影响系统的性能指标的主要因素,用最优控制问题的理论设计2000KN 电液伺服试验机,通过实验和调试,结果说明,用数学解析法设计系统比用古典频率法设计系统显得更优越。
In this paper, the working conditions of the electro-hydraulic servo testing machine and the main factors affecting the performance of the system are analyzed. The 2000KN electro-hydraulic servo testing machine is designed based on the theory of optimal control. The results show that the system is designed by mathematical analysis Than classical frequency method design system appears to be superior.
