考虑管道效应的液压伺服系统稳定性判定

Stability of Hydraulic Serve Systems Considering the Effect of Pipeline

对考虑管道效应的电液位置伺服系统的数学模型进行了合理的简化，提出了一种实用的基于Nyquist判据的系统稳定性判别方法．该方法可根据管道参数确定系统稳定的开环放大系数．

Based on the reasonable simplifying the mathernatical model of hydraulic position serve systems concerning the effect of pipeline, a stability criterion acting on Nyquist criterion is provided. The amplification coefficient of a open -loop on the stability of systems can be determined by the criterion.
