At first, the dynamic mathematic model is created in the light of the known dimensions and structure. then base on the mathematic model, dynamic analysis of the system is studied by drawing the open - loop bode diagram closed - loop bode diagram and step response curve using the analysis and calculating function of matlab. the influence factor on frequency character steady and performance of the system is also analyzed
首先，根據已確定的尺寸參數和結構需要，計算並建立起系統的動態數學模型，然後在已知系統數學模型的基礎上，利用matlab語言強大的分析計算功能，對系統進行動態分析，通過畫出系統的開環bode圖、閉環bode圖及系統的階躍響應曲線，分析了系統的頻率特性、穩定性及系統性能的影響因素。 -
First, the working principles of the combustion control system of marine main boiler in present use and its disadvantages are discussed in the paper ; in the light of the structure and motion traits of marine main boiler, the combustion control systems of single and double cross amplitude limits are designed. at the same time, the schematic diagram of system and recovery curves of some relative parameters are given, the system working principles and its advantages and disadvantages are discussed. based on the combustion control system of dual - crisscross amplitude limit, by selecting the independent variable, the fixed offset is improved into variable offset, the combustion control system of variable offset dual - crisscross amplitude limit is designed
首先討論了目前船用主鍋爐燃燒控制系統的工作原理及存在的不足；針對船用主鍋爐的結構及運行特點，設計了單交叉限幅燃燒控制系統和雙交叉限幅燃燒控制系統，同時給出了系統原理圖及有關參數的過渡過程曲線，討論了系統工作原理及優缺點；在雙交叉限幅燃燒控制系統的基礎上，將固定偏置經過自變量的選取，改進成變偏置，設計了變偏置雙交叉限幅燃燒控制系統，給出了系統原理圖及有關參數的過渡過程曲線，同時也給出了空氣壓力和燃油流量正負偏置函數與變偏置折線函數的關系式。 -
In the light of the method of top - down, the author put forward the concept of product function structure tree, which was used to express the product ' s function structure during the conceptual design. based on it, the product structure was expressedthe paper studies the definition of the function model which supports the method of top - down design, and the expression of function model based on binary - tree was also put forward in the thesis. for the abstract description of parts in the assembly level and the integration with other systems during the whole life circle of the products, the concept of assembly model was presented, the definiton, classfication and expresstion method of assembly feature was studied in this thesis. the representation of assembly relationship and data structure of the assembly model based on diagram was further studied. for the constraints transfer between function model and assembly model, an hierarchical component model is presented. an arithmetic of the change of assembly relationship when assembly model changing was also studied. fmally, a system named fb - tpms, which using object oriented programming technology and pro / toolkit, was developed
為了支持在裝配層次上的零件的抽象建模，提出了骨架模型的概念，並討論了裝配模型的建立方法。根據前述裝配模型有關研究，探討了從功能模型到裝配模型以及從上一級裝配模型到下一級裝配模型的數據和約束傳遞問題，並用層次化單元裝配模型得以解決，同時提出了裝配模型變動時引起的裝配關系的變化的有關演算法。在論文的最後部分用用面向對象的程序設計方法，結合課題要求，研究了支持自頂向下設計方法的裝配建模系統fb - tpms 。
