  1. Power bond graph is used to established the bond graph model of the lifting and dropping of hydraulic pile hammer and state space equation in the paper for hydraulic pile hammer is perplexing nonlinear system. in order to attain the graph that pressure, position, velocity, acceleration vary with time in the course of driving pile simulation procedure solving state space equation is designed on the basis of combining four - order runge - kutta method with predicator - corrector method, dynamic simulation of the hydraulic system is studied in matlab 6. 5. it is convenient to analyse dynamic characteristics of the hydraulic syste m, beneficial to the design and parameter optimization of the hydraulic system. in the final part of the paper, under detailed analysis of the control characteristics for double - acting hydraulic pile hammer with double cylinders, control system based on the programmable logic controllers founded on technology of modern compute is designed

    由於液壓打樁錘液壓系統是一個復雜的非性系統,本文採用功鍵合圖法建立液壓打樁錘上行、下降的鍵合圖模型和狀空間方程,通過四階龍格?庫塔法和預估?校法相結合編制了模擬程序對狀空間方程求解,在matlab6 . 5中進行液壓系統的動模擬,獲得液壓打樁錘運動過程中壓力、位移、速度、加速度等隨時間變化的圖。此圖方便了對液壓系統動特性分析,為液壓系統的設計和參數優化提供了有益的借鑒。最後,在深入分析雙缸雙作用液壓打樁錘控制系統的功能要求后,採用了以現代計算技術為基礎的新型工業控制裝置? plc可編程式控制制器,設計出了雙缸雙作用液壓打樁錘的電器控制系統。
  2. Meanwhile, we have gained some achievement. 1. based on error variety of nonlinear control curves of ld output laser power by optoelectronic feedback measured, we take advantage of window pid control algorithm to gain high stability of laser power and reduce error amends at mostly

    1 、基於光電池檢測ld光功輸出的非性控制產生的誤差變化,將特性利用軟體的窗口控制演算法實現區域控制,進而有效的對ld工作電流進行pid穩控制和光功參數顯示,且激光器的光功輸出和激光通過分光鏡後送入光電池放大電壓量和單片通過計算使到誤差修量達到最小,從而使光功控制達到最佳效果的變化關系。
  3. This paper focuses on the research of fuzzy control, especially rule self - adjusting fuzzy control method. by theoretic analysis and simulations, the influences of parameters and system performance characteristic of some kinds of rule on - line self - regulating fuzzy control methods are discussed, and a novel real - time self - adjusting fuzzy control method ( vsrsafc ) is proposed from the diagrammatic point of view. in vsrsafc, the slope of the rectifying curve of rule scaling factor a is altered by the fine - tuning and coarse tuning combined mechanism to adjust the fuzzy control rules according to error e and error change ec, which more coincides with characteristic of system response than the conventional self - adjusting method that adjusts rule scaling factor only according to the error e, and has better static and dynamic performances than the latter

    其中變斜規則自調整模糊控制的效果較為明顯,它是基於插值的非性規則自調整模糊控制的引申以及常規全論域規則自調整模糊控制的改進,該方法採用粗、細調結合制,通過改變規則調整因子的修,使系統同時根據誤差e以及誤差變化ec在調整模糊控制規則,比傳統的僅基於系統誤差e的自調整方法更符合系統響應特性,可獲得更好的動靜控制性能,特別是對于系統參數發生改變、控制參數選取不當等不良狀況,控制器仍能較快自調整,具有較強的在自適應能力。
