  2. A method of fuzzy optimization design based on genetic algorithm is presented as a new method of parameter optimization design for dc double closed loop speed adjusting system. the method covers three steps. firstly, speed overshoot rate and settling time are chosen as performance indice according to the demand of engineering. these indice are normalized by using fuzzy membership function and then weighted to form objective function of optimization model of the system. secondly, the dynamic response curve of the system with corresponding parameters and peoformance indice are obtained by computerized numerical calculation and simulation. finally, parameters of engineering design are expanded as searching space ; and parameters of speed regulator and current regulator are taken as genes in chromosome. these genes in searching space are optimized to get best solution by way of genetic algorithm. as shown by experimental results, the parameters designed by this method are capable of significantly improving performance indice of the system, which proves that it is a practical and effective method

    提出一種基於遺傳演算法的直流雙閉環調速系統參數優化設計方法.根據工程技術的要求，選用速度超調量和過渡時間作為參數優化性能指標.將該指標用模糊隸屬度函數歸一化，再加權平均形成系統優化模型的目標函數.採用計算機數值計算方法，通過模擬獲得系統對應參數的動態響應曲線及其性能指標.最後以工程設計的參數為搜索范圍，以速度調節器和電流調節器的參數為染色體中的基因，通過遺傳演算法在搜索范圍中優化這些基因，獲得優化解.實驗結果表明，所設計的參數能使系統性能指標有顯著提高
  3. Abstract : a problem resolution can be represented by a series of chromosomes in genetic algorithm ( ga ). in the evolving process of reproduction, crossoves and mutation to chromosomes, a chromosome which is fitter to the enviroment can be obtained as the resolution of the problem. the membership functions and control rules are optimized by using ga, the design and adjustment of fuzzy controller are also improved

    文摘:遺傳演算法是將問題的求解用染色體的形式表示，在其復制、交叉、變異的進化過程中收斂為一個最適應環境的染色體，即為問題的解.用遺傳演算法對模糊控制中的隸屬度函數進行編碼，確定適應度函數，作遺傳運算與微量調整，可實現對隸屬度函數及控制規則的優化，改善模糊控制器的性能
