摘要:

为了使全液压矫直机的液压伺服系统控制更精确、系统更稳定,从工程实际出发,以阀芯控制电压为输入信号,液压缸位移为输出信号,建立了基于高频响非对称比例伺服阀控制非对称缸的数学模型,并且通过仿真分析和实验室应用,验证了该系统模型的正确性。

关键词: 高频响非对称比例伺服阀, 非对称缸, 负载压力, 负载流量, 综合泄漏系数

Abstract:

For a more accurate and more stable hydraulic servo system of the full-hydraulicleveler,from engineering reality that the spool control voltage was as an input signal and the cylinder displacement was as an output signal,a mathematical model was established herein based on high frequency response asymmetrical proportional servo valve controlling asymmetrical cylinder.The model was proved by simulation analysis and applications in the laboratory.

Key words: high frequency response asymmetrical proportional servo valve, asymmetrical cylinder, load pressure, load flow, complex leakage coefficient
