在控制氣壓系統時，氣壓閥可說是時常使用到的控制元件，不論是方向、流量或是壓力控制都有機會用到。故氣壓閥的改良研發對控制氣壓系統有重大影響，本文利用了動圈式線性馬達、基因演算法及模糊控制理論來進行改良。
本文選用了動圈式線性馬達作為氣壓閥閥軸之致動器，利用其在短行程時能提供高響應、線性出力的優點，以達到氣壓閥響應改善。對氣壓系統來說，要獲得精確的數學模型是很困難的，故本文使用對精確數學模型要求度低的基因演算法和模糊控制理論來設計控制器。
本文應用了非線性PI控制器及非線性自調式模糊控制器。實驗結果兩者的從零到100%行程最大流量(218L/min)的上升時間在時分別為4ms和3.5ms，使氣壓伺服閥具有快速的響應。

In this paper, the moving coil motor is used as the actuator of valve shaft in the pneumatic servo valve. The moving coil motor can provide some advantages, like: the high acceleration, linear output in short stroke. We use these advantages to improve the performance of the pneumatic valve.
For the pneumatic system, it is very difficult to obtain an accurate mathematical mode, so this paper uses the fuzzy control theory that do not require an accurate mathematical model to design the controller.
From the experimental results, it is observed that the rise time from zero flow rate to maximum flow rate (100% stroke) is close to 3.5ms. It can be seen that this pneumatic servo vale can be controlled very quickly.
