電液比例閥控斜板式變量泵應用於液壓伺服系統，常造成穩定性不良問題。本文整合泵浦及其控制器，建立其數學模型，以數學模擬研討電液變量泵之壓力及流量輸出反應。分析變量泵設計參數與其動態反應之關係，設計流量壓力混合控制器，控制電液變量泵斜板偏轉角度及輸出壓力，改進其高速反應穩定性。模擬結果及實驗結果得到穩定及快速之壓力輸出及斜板偏轉角反應特性。

The swash plate variable displacement pump applied to an electro-hydraulic servo system usually induces unstable performance. In this paper, the mathematic model of variable displacement pump and its controller is established. A hybrid controller of pump is designed by analysis of pump parameters and the corresponding dynamic responses for improving the stability of high performance pump operations. The flow and pressure variations are investigated by mathematic simulation. The simulation and experiment results show the favor stable pressure and swash plate angular displacement responses achieved.
