  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. Simulation and test of rocket initial disturbance

  4. Base on review of existed study and application in suppressing cable vibration in the world, technique of mitigating cable vibration with viscous damper and mr damper has been investigated in this dissertation, and the main contents and progresses in form of summary are as following : 1 the motion differential equations of the cable - damper system are formatted, which take into account these factors, such as the inclined angle, sag, stiffness etc. coupling motion between cable and deck is studied with analytical and numerical method. numerical results show that large amplitude vibration of cable with beat rhythm will occur when exciting frequency of deck equals two times modal frequency of cable

    本文在對國內外斜拉索振動控制研究與應用現狀進行綜合評述、分析的基礎上，針對上述問題進行了深入研究，具體的研究內容和取得的成果包括： 1 、建立了斜拉索-阻尼器系統運動方程，對拉索與橋面的耦合振動作了分析和研究，數值結果顯示當橋面激振頻率等於某階拉索模態頻率的兩倍時，很小的初始擾動將引起拉索的大幅振動，並呈現拍振的特徵，與實測的拍振信號一致。
