其中，第二章對我國糧食流通體制的演變歷程作了一個系統的回顧；第三章在第二章的基礎上，深入分析了我國糧食流通體制改革多次出現反復的原因，作者認為，從深層次的原因來看，主要是由於糧食價格形成機制不健全、糧食市場主體發育滯后、產銷區之間的利益分配機制難以協調以及糧食進出口調節機制的滯后性等原因造成了我國糧食流通體制改革的多次反復，而這些問題的存在歸根到底都與我國缺乏運作有效的農產品期貨市場有很大的關系；第四章對我國農產品期貨市場的發展歷程及其存在的問題進行了探討，通過具體的分析，作者認為，由於當時我國的農產品期貨市場本身還很不成熟與完備，因此，它無法在我國前兩輪糧食流通體制改革中發揮其固有的功能和作用。To plants with big time delay, the neuron pid control method with fuzzy - tuning gain is proposed. being used to control the water temperature process, the simulation tests results prove the validity of the proposed method
針對具有不確定性的大純滯后對象，提出了增益模糊自整定神經元pid控制方法，並以具有大純滯后特性的水溫調節過程為背景，進行了模擬實驗，模擬結果證明了該方法的有效性。There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control ， decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively
現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象，它們中有些還是具有強非線性特性的對象或多變量耦合系統，採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段，則需要建立被控對象的數學模型，而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。Dynamic matrix control ( dmc ) can directly treat with objects with pure delay, has strong adaptability to large inertia, approved tracking performance and better robustness, but primary steam temperature object and boiler fuel regulating object are both intricate objects with large inertia and time delay, which are difficult to obtain perfect control effect using routine pid cascade control
