摘要

为了验证和优化电液伺服系统的设计过程,本文建立了负载可调电液伺服负载试验台。在对试验台进行结构分析的基础上,建立了闭环转矩和位置控制的数学模型。经过理论计算和模型简化,设计了一种由前馈控制和PID控制组成的复合控制器。随后,本研究重点进行了转矩环实验。通过实验验证了设计过程的正确性和可行性。试验得出的一些定性结论可为类似应用提供参考。

Compound control on electro-hydraulic servo loading test bench
In order to verify and optimize the design process of electro-hydraulic servo system, this paper set up a load-adjustable electro-hydraulic servo load test bench. Base on the structural analysis of test bench, the mathematical models of closed-loop torque and position control are established. After theoretical calculations and model simplification, a compound controller consisting of feedforward control and PID control is designed. Later, this study focused on the torque loop experiment. The correctness and feasibility of the design process can be verified via experiments. Some qualitative conclusions from the test can provide some reference for the similar applications.
