In this paper generic model control is applied to the design of controlling law of the nonlinear power propulsion system, at the work state of constant depth and variable speed, constant speed and variable depth movement of torpedo. then the simulation program of the torpedo thermal power digital simulation system comes forth which can be used for the dynamic simulation of the performance of the process of open - loop constant depth and open - loop constant speed, the process of close - loop constant depth and close - loop constant speed
本文採用一般模型控制的基本原理，對非線性動力推進系統進行控制律的綜合，設計了魚雷恆深變速、恆速變深控制的閉環控制規律，開發了魚雷熱動力系統數字模擬軟體，對魚雷熱動力推進系統的典型工況：開環恆深、開環恆速以及閉環恆深、閉環恆速進行動態模擬。 -
Ball valve uses ball with circular hole as open - close part, through turning ball with stem to realize on - off movement. ball valve is mainly applied to stop, distrubute and change flowing direction of medium
球閥是用帶圓形的通孔的球體作啟閉件，球體隨閥桿轉動，以實現啟閉動作的閥門，球閥在管道中主要用於切斷，分配和改變介質流動方向。 -
