介绍了50t疲劳试验机液压伺服力控制系统,对其进行数学建模,分析其动态特性,采用双惯性环节对其动态特性进行补偿,仿真结果证明了双惯性环节拓展了液压伺服力控制系统带宽。
This paper introduced the 50t fatigue testing machine hydraulic servo control system, mathematically modeling it, analyzing its dynamic characteristics and using double inertia to compensate the dynamic characteristics of the system. The simulation results proved that the dual inertia links extended the hydraulic servo control system bandwidth .
