摘要: 分析了直接轉矩控制的基本原理。系統采用高低速均適用的磁鏈混合觀測模型。提出一種改進的磁鏈和轉矩控制器,同時給出了相應的電壓矢量選擇規則.還提出了開關頻率自調整控制的思想。在此基礎上,設計了8098單片機全數字控制系統,用它分別進行了數字仿真和實時控制,并給出實驗結果。Abstract: The dasic principle of direct self control system is analysed. A mixing type of flux estimator is empolyed at high and low velocities.A kind of improved flux and torque controller is presnted and the corresponding selecting rule of voltage vectors is showed at the same time.It puts forward that the control system by 8098 single chip miciroprocessor is desingned. Simulation and experimental results are showed at the end.
