Manually Controlled Digital Open Loop Servo-Valve Actuator

9361031伍德沃斯在本研究项目中，研制了一种数字开环伺服阀执行器。与传统系统相比，这种阀门执行器的主要优势包括更低的成本、更高的性能、更高的可靠性和重复性、更高的电气和液压效率、可再生的能量捕获以及对流体污染堵塞的不敏感性。由于阀门是以全开或全关闭的方式运行，因此控制系统允许阀门将流体流量分解为小增量。阀门的高速使微小的运动控制和精确成为可能。该系统的潜在应用包括机器人、自动化制造、飞机飞行控制和发电。***

9361031 Woodworth In this research project, a digital open loop servo-valve actuator is developed. The major advantages of such valve actuator over conventional systems include lower cost, higher performance, greater reliability and repeatability, higher electrical and hydraulic efficiency, regenerative energy capture and insensitivity to fluid contamination clogging. Since the valves are operated as either fully open or fully closed, the control system allows the valves to literally break up the fluid flow into small increments. The high speed of the valve makes small movement control and precision possible. Potential applications of the system include robotics, automated manufacturing, aircraft flight controls and power generation. ***
