  1. The control system of mould level is crucial to improve the slab quality in the continuous casting process, pid controller is used in the traditional mould level control, and it has some defaults, such as : at the start - up or finishing period of casting or during the changeover of tundish, pid control has a bad effect, its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate, and pid control can not overcome the disturbances resulted from the change of casting speed

    結晶器液位控制系統是提高連鑄產品質量的關鍵環節，傳統的連鑄機液位控制方法採用常規的pid控制，存在如下不足：開始、結束澆注和換中間罐澆注時，控制效果差，超調量大，過渡時間長；塞棒頭和浸入式水口被腐蝕后引起控制精度差；浸入式水口堵塞物的突然脫落所引起的液位劇烈波動；無法克服拉速波動引起的擾動。
  2. The instantaneous torque measurement system has been improved, which uses slip ring to transmit signal, improved measuring accuracy and stability, the mechanism of occurring of instantaneous maximum torque has been understood during changeover of the main engine

    改進了集流環傳輸信號的瞬時扭矩測量系統，提高了測量精度和穩定性，進一步認清了在主機切換過程中瞬時扭矩的極大值產生的機理。
  3. At present more and more changeover company property right, mechanism and legal entity execute our country competitive bidding system, yearly salary is made, it is the management the enterprise actually authority pays entrepreneur of take office estate in the hand

    目前我國越來越多的轉換企業產權、機制以及企業法人實行招標制、年薪制，實際上就是將企業的治理大權交到職業企業家手中。
  4. In order to enhance the level of automation, the said governing system has been retrofitted by using technical scheme, in which the rexa astuator is taken as a changeover gear, and the force - driven actuator as a servomotor, obtaining satisfactory retrofit result, providing new way for retrofitting the governing system of similar type units

    為提高機組的自動化水平，採用以rexa執行器為轉換裝置和力驅動執行機構油動機的技術方案對其進行了改造，取得了滿意的效果，為同類型機組調節系統的改造提供了新途徑。
  5. However, it has been very little practice of such devices in main naval war ships of china, therefore it is of great significance to set up a measurement and control system of codog power plant and to simulate, and to research the process of the main engine changeover

    我國海軍應用這類動力裝置的經驗甚少，因此建立codog物理模擬實驗臺的測控系統並對其切換過程進行模擬和實驗研究具有重要意義。
  6. Based on the improved codog power plant experiment rig of harbin engineering university, the thesis has set up the displacement measurement system of the middle slippage of the synchronous self shifting ( s. s. s. ) clutch at the first time, and obtained the curve which follows the time variability of the axial displacement when engaging or disengaging and reflects the dynamic change of the s. s. s. clutch for the main engine changeover of codog power plant experiment rig

    本文的研究是建立在對我校原有codog物理模擬實驗臺改進的基礎上進行的，首次建立了三s離合器中間滑移件位移測量系統，獲得了三s離合器中間滑移件在嚙合及脫開過程中的軸向位移隨時間的動態變化曲線，該曲線從一個側面反映了切換過程中三s離合器的動態變化。
  7. The program software and design hardware realize the control of the digital governor of n6136 turbocharged diesel and speed adjust system of sla - 02 gas turbine, they can control the rotating speed of the diesel and gas turbine in the forward experiment and can make the main engine changeover processes of the codog physical analog experiment rig possible to be controlled through computer, therefore to set up a solid foundation for the research of possible projects in the changeover processes

    通過軟體編程和硬體設計實現了對n6135柴油機的電子調速器和s1a - 02甲燃機的調速系統進行控制，能夠在實驗前和實驗中實時的對柴油機和燃氣輪機的轉速變化進行設定和控制，使codog物理模擬實驗臺主機切換過程實現計算機控制，為實現多方案切換過程研究打下堅實的基礎。
