  3. Aim at the dtc ' s blemish mentioned above and the direction of dtc technique development, the dissertation put great emphasis on the work as follows, with an eye to exalt dtc system function : ( 1 ) a new speed - flux observer of an induction motor is proposed to enhance the accuracy of flux observing, which is an adaptive closed - loop flux observer and different from the traditions. a new adaptive speed - observation - way is deduced out according to the popov ' s stability theories ; ( 2 ) to improve the performance of dtc at low speed operation, we have to exalt the accuracy of the stator flux estimation and a new way of bp neural network based on extended pidbp algorithm is given to estimate and tune the stator resistance of an induction motor to increase the accuracy of the stator flux estimation ; ( 3 ) digital signal processor is adopted to realize digital control. an device of direct torque control system is designed for experiment using tms320lf2407 chip produced by ti company ; ( 4 ) bring up a distributed direct torque control system based on sercos bus, sercos stand for serial real time communication system agreement which is most in keeping with synchronous with moderate motor control ; ( 5 ) the basic design frame of the hardware and software of the whole control system is given here and some concrete problem in the experiments is described here in detail

    針對上面提到的直接轉矩控制的缺陷和未來直接轉矩控制技術發展方向,本論文重點做了以下幾個方面的工作,目的在於提高dtc系統的綜合性能: ( 1 )提出一種新型的速度磁鏈觀測器,新型的速度磁鏈觀測器採用自適應閉環磁鏈觀測器代替傳統的積分器從而提高磁鏈觀測的精度,並且根據popov超穩定性理論推導出轉速的新型自適應收斂律; ( 2 )改善系統的低速運行性能,主要從提高低速時對定子磁鏈的估計精度入手,提出了一種提高定子磁鏈觀測精度的新思路? ?利用基於bp網路增廣pidbp學習演算法來實時在線地修正定子電阻參數; ( 3 )採用數字信號處理器dsp實現系統全數字化硬體控制,結合ti公司生產的tms320lf2407晶元,設計了直接轉矩控制系統的實驗裝置; ( 4 )提出了基於sercos總線網路化分散式的直接轉矩控制系統, sercos ( serialrealtimecommunicationsystem )是目前最適合同步和協調控制的串列實時通信協議; ( 5 )基本勾勒出整個控制系統的硬體和軟體設計基本框架,詳細描述一些實驗中的具體的細節問題。
