摘　　要：由于液压伺服系统普遍存在非线性,使用传统的机理建模方法就难以建立准确的数学模型,也不能准确地反应系统实际情况。在合理设计辨识试验的基础上,对系统进行非参数模型辨识,较为准确地辨识出了对象的脉冲响应过程,并推导出系统的传递函数。The precise mathematic model was hard to be developed with conventional mechanism analysis method because of the non-linear factors of the hydraulic servo system. The non-parameter and parameter model of hydraulic system was identified based on the well-designed identification experiment. The impulse response process of the system was identified, and the system transmission function was developed.
