| 摘 要： | 2D数字伺服阀为利用阀芯的双运动自由度原理设计而成导控型阀。阀芯的旋转由步进电机驱动；阀芯的轴向运动则由两端阀腔的静压力推动。为了克服传统的步进式数字阀（离散式比例阀）所固有的响应速度与量化误差的矛盾，步进电机采用特殊的跟踪控制算法，实现其输出角位移连续控制。本文主要对其频响特性进行分析。

| Abstract: | 2D digital servo valve is developed by utilizing both rotary and linear motions of a spool. The rotary motion of the spool is driven by a stepper motor; While the linear motion is actuated by pressure difference of two end spool chamber. In order to sustain the quantative accuracy and dynamic response, a special algorithm is introduced to continually control the angular displacement of the stepper motor. In this paper, we study on the frequency response of 2D digital servo valve. |
