解釋
負荷壓力反饋-
At last this chapter researches two ways that make system performance optimal, test way and pole allocation way. the affections of feedback parameters, air pressure and load quality are analyzed. chapter 5 introduces the theory, application and foreground of the vsc ( variable structure control ) system
最後一部分研究了實現系統狀態反饋控制的方法，包括試湊法和極點配置法，並分析了各反饋參數、氣源壓力和負載質量對控制性能的影響。 -
Because deh system can use feedback signal of the first class pressure as practical power of turbine, it can avoid the reverse control, have the good ability of anti - disturbing. by the sophisticate control logic deh can make swift change of the control demand for following best value according to the circumstance, largely improved the dynamic characteristic when the unit sundenly discharge the full load
Deh系統控制器中的pid系數可根據試驗情況方便的調整，實現較好的動態特性，並可使調汽門動態過開，使再熱機組有良好的一次調頻能力； deh系統可採用調節級壓力做為汽輪機實發功率的反饋信號，避免出現反調現象，抗內擾和外擾能力強。 -
Now design efficiency of common gas boiler can reach 90 percent or so, but various factors such as load, fuel quality, work condition and pressure which result in uncompleted burning of gas and excess air, decrease boiler hot efficiency and cause resources waste and environment pollution. considering these it is essential to adopt closed loop feedback control to boiler burning system
現今，一般的燃氣鍋爐設計效率均能達到90 %左右，但在實際運行中，因負荷、燃料品質、工作環境、壓力、混合情況等因素的影響，往往造成燃氣不完全燃燒或空氣過量，使鍋爐熱效率降低，造成能源浪費與環境污染，在這樣一種背景下，有必要對其燃燒系統進行閉環反饋控制。 -
This paper analyses the type, function and characteristics of usual proportional control valves and raises a new modificative version in the light of their drawback. that is, basing on the principle of flow amplification and electrical feedback and throughout calculation and analysis on flow closed loop control and pressure flow combination., determination of the minimum controlled pressure difference as well as flow controlling range and structure of main valve and research of the dynamic and static characteristic, the paper puts forward control principle of " flow - load pressure change - displacement revision " and pressure / flow double closed loop, and further expounds that using a proportional controller and a electric mechanical transducer can separately serve the control function of pressure or flow as well as flow pressure combination
本論文分析了目前常用比例閥的類型、功能、特性，並針對其不足提出新的改進方案，即：以流量放大，電反饋兩個原理為基礎，通過對流量閉環控制及壓力流量復合的計算分析、確定上最小控制壓差及流量控制范圍，確定主閥結構、功能特性研究等，提出了「流量? ?負載壓力變化? ?位移修正」的控制原理和壓力流量雙閉環控制原理，並進一步論述了利用一個比例控制器和一個「電?機械轉換器」就可完成獨立的壓力或流量控制功能以及流量壓力復合控制功能。
