  1. Comparing and analyzing the synchronous control strategy, which brings up the new method to control the double un - symmetry jars proceed synchronously with the combination of proportional valve and servo valve, which forms closed loop control ; basing on the above methods, models are made to get mathematics models of position control system and to analyze system model theoretically by using pid controller, we can realize regulating parameters, minimizing synchronous errors and enhancing the dynamic performances ; the simulink tool box in matlab software is used to imitate the system according to the model, which not only makes the result visual and easy to adjust the parameters in interactive way but also lets us understand the effects of different parameters and optimizes the dynamic properties. the theory of plc control in dshp is discussed after advanced understanding of the system movements. hardware design and general regulation are given on the base of siemens company products s7 - 200 plc

    本文根據大量的國內外文獻，對研配液壓機的工作原理及設計結構進行了簡介；對位置同步的控制方法進行了比較分析，提出比例閥和伺服閥復合控制的閉環結構來對非對稱雙缸進行同步控制電液比例同步控制方案；在此基礎上著重對比例閥控非對稱缸建模，最後得到位置控制系統的總體數學模型，從理論上對同步系統動態特性進行了分析，並用pid控制器進行參數整定，減小雙缸同步誤差、提高系統的動態響應性能；其中控制性能的分析藉助于matlab軟體中的simulink工具箱，由已建立的數學模型形成模擬模型，得到可視化的模擬結果，從而利於交互方式下調整參數，了解不同的參數對系統的影響，優化同步系統的動態性能；在深入了解系統的動作特性后，對plc控制研配液壓機的原理進行了探討，針對siemens公司s7 ? 200型plc給出了硬體設計的總體規劃，編制出研配液壓機動作控製程序，在編程中著重研究位移傳感器與plc的通訊、雙缸同步運行的pid控制在plc上的實現及bcd碼撥盤輸入程序的植入問題。
  2. The control precision of the slider with 2400mm effective stroke can reach 0. 05mm. the properties of the position control system are not exigent, only the dynamic non - overshooting and the stable - state - precision are considered. the system has given out satisfactory result when used in practical engineering, 0. 03mm position control precision has been achieved, on account of dead band, the performance of proportional valve is worse than that of servo valve, but some advantages of proportional valve has made it more fit for industrial control

    系統方案採用重復性能（反向回差）好的比例方向閥，使有效行程為2400mm的滑塊控制精度達到0 . 05mm ，位控系統快速性要求不高，主要考慮系統穩態重復精度，此方案在實際工程中已經取得了滿意的效果，位置控制精度達到0 . 03mm ，可以取代同類產品中日本川崎重工的泵控系統。
  3. Until now, there have had the single way proportional valve controlling the power or the route, double way ratio valve controlling the orientation. they cover flux control, pressure control, velocity control and position control. according to these functions, ratio amplifier has single way or double ways type amplifier

    由於比例閥已經發展出單通道力、行程控制比例閥，雙通道方向控制比例閥，廣泛用於流量、壓力、速度、位置控制等環節中，比例放大器也本著這些功能研製出了單、雙通道的比例電控器。
  4. By measuring the differential pressure and using a regulated valve position to balance the flow rate to the same % dfr as the index valve, the next most favored branch can then be proportionally balanced as above and so on - finally after all the branches have been proportionally balanced the branch valves can then be proportionally balanced to each other

    通過測量壓差和使用一個將流動速率平衡到與指標閥相同的% dfr的已經調節開啟位置的閥門，次容易分支隨后也可以合上述過程一樣被比例平衡，等等-最後，在所有分支都被比例平衡之後，分支閥門隨后也可以互相比例平衡。
  5. Each balancing valve shall be in the full open ( nominated ) position prior to commencing the proportional balancing of water distribution systems

    在水分流系統開始進行比例平衡之前，每個平衡閥應該位於全開（指定）位置。
