現有液壓實驗臺控制系統由PLC、計算機控制（計算機內部裝有數據采集卡，用來完成對比例閥和伺服閥的測試）、手動、自動控制等方式組成。液壓實驗臺的自動化程度比較高。但隨著液壓技術和計算機技術的高速發展，現有的液壓實驗臺也有一定的局限性，主要表現在下面兩個方面：

（1）液壓實驗臺測試壓力較低、輸出流量比較小。從成本和學生使用安全角度考慮，目前實驗室內的兩臺試驗臺，一臺壓力為15MPa左右，另一臺最高壓力為22MPa左右。變量泵液壓系統的最大輸出流量為32L/min，定量泵液壓系統的額定流量為12L/min。
2）現有液壓實驗臺可以做通用液壓元件的實驗，卻不能滿足特殊液壓元件（如插裝閥和多路換向閥）的測試。
（1）Hydraulic testing bench has the characteristic of lower test pressure and small out flow. Out of consideration for the cost and students use safety ，the two test bench in laboratory at present both have the characteristic of lower test pressure and small out flow. Quantitative pump hydraulic system has the pressure of below 15MPa and flow below 12L/min，the other one is variable pump system which has the pressure of below 22MPa and flow below 32L/min.
（2）The existing hydraulic test bench can test experiments of general hydraulic components while as can't test special hydraulic components（such as cartridge valves and multi-way directional valve）.

    綜合上面兩個原因，如果想使液壓實驗技術和液壓技術的發展同步，可以采取優化現有液壓實驗臺的方法來實現。本文中，在參考YCS-DII電液伺服比例實驗臺的基礎上，完成實驗臺優化中增設液壓回路的設計，完成優化液壓實驗臺電氣系統并繪制出相應的控制圖。通過仿真軟件AMESim的應用，為增設液壓回路建立仿真模型并設置參數，從而得到比較合理的液壓系統和比較理想的元件參數。
