  1. So the paper combined the fuzzy logic control and recurrent neural network, and the recurrent fuzzy neural network ( rfnn ) controller is introduced into the speedsensorless vector control system. moreover, an online parameter training methodology, which is derived from the lyapunov stability theorem and gradient descent method is proposed to increase the learning capability of the rfnn. the rfnn controller has a better performance than the pi controller system ; the effectiveness of the proposed control scheme is verified by simulation results

    因此論文將模糊控制和具有優越動態性能的遞歸神經網路結合起來，取長補短，提出了一種遞歸模糊神經網路控制方法，利用神經網路來實現模糊推理，可動態的調整隸屬函數的形狀、位置以及神經網路遞歸權值，並對其與pi控制器的交流調速控制系統進行了模擬比較，模擬結果表明與普通的pi控制器相比較，遞歸模糊神經網路控制器有較好的動態性能，控制器的收斂速度快、靜差小，系統在遇到參數發生變化和外部不確定性問題時魯棒性、抗擾動性有明顯的提高。
  2. Then detailed, analyze the agriculture public fiscal expenditure scale through the years, made a conclusion that the total amounts of agriculture fiscal expenditure increase continuously, however the scale descends continuously. comparing with other province, henan agriculture public finance expending is very low in scale. inquiry into agriculture public finance expending scale descent, and predict future 10 - year agriculture public finance expenditure total amount ; make use of the quantitative analysis method analysis henan province agriculture public finance expenditure benefit, include the agriculture public finance expenditure to the contribution of agriculture increase, the flexibility coefficient of the agriculture public fiscal expenditure, agriculture public fiscal expenditure construction performance etc, and analyze to make the factor that invite performance ' s develop ; finally, on the above analytic foundation, put forward public finance frame bottom agriculture public fiscal expenditure funds management mode

    本文首先在導言中闡述了國內外關于農業財政支出的相關理論，為后續的研究提供理論基礎和分析的方法論；然後詳細、具體地分析歷年來河南農業財政支出規模變動情況，得出農業財政支出總量雖不斷增長，支出規模卻在波動中不斷下降、與其它省份相比河南農業財政支出規模偏低的結論，探討了河南農業財政支出規模下降的原因，並預測未來十年河南農業財政支出總量；接著運用定量的分析方法分析河南農業財政支出效益情況，包括農業財政支出對農業增長的貢獻，農業財政支出的彈性系數變化，農業財政支出結構效益等，並分析制約效益發揮的因素? ?農業財政支出資金管理不善；最後，在上述分析的基礎上，提出公共財政框架下農業財政支出資金全過程管理模式，具體包括：農業財政支出投放體系、支農資金管理體系、支農項目管理體系、評估體系、決策體系以及監督體系等六大體系。
  3. Using the indices of trajectory follow error and steering busyness in evaluation of the steering stability, a quadratic form performance index function for the neuron learning was established and the tuning of the connection weight values of the single neuron controller was realized using the algorithm of gradient descent

    利用操縱穩定性評價中的軌跡跟隨誤差和方向盤忙碌程度的評價指標，建立了神經元學習的二次型性能指標函數，並採用梯度下降演算法實現了單神經元控制器的滾接權值的調整。
