电液伺服阀是电液伺服控制系统中一个最基本的组成部分,其数学模型的误差直接关系到系统的数学模型的准确程度,进而影响控制算法的效果及系统的控制精度。但是,由于液压系统所固有的不确定因素,伺服阀的数学模型不可能用恒定不变的理论公式来描述。因此,如何准确地确定电液伺服阀的数学模型,历来是电液伺服系统设计师们所最为关心和必须首先解决的问题之一。本文
Electro-hydraulic servo valve is one of the most basic components of electro-hydraulic servo control system. The error of its mathematical model is directly related to the accuracy of the mathematical model of the system, thus affecting the control algorithm’s effect and system’s control accuracy. However, due to the inherent uncertainties of hydraulic systems, the mathematical model of servovalve can not be described by a constant theoretical formula. Therefore, how to accurately determine the mathematical model of electro-hydraulic servo valve, electro-hydraulic servo system designers has always been the most concerned and must be the first to solve one of the problems.
