中文摘要 | 本文介紹一具有線上估測轉子時間常數之強健型定子磁場導向感應馬達驅動系統,並利用一混合滑動控制器控制其速度。線上估測轉子時間常數之方法是結合模式參考適應控制系統及一能量函數,並將時間常數估測值使用在定子磁場導向之電流解耦控制器中。另一方面,利用結合積分比例速度控制器及積分運算滑動面之混合滑動模式控制器來增強速度控制回路之強健性。 |
英文摘要 | A robust stator-flux-oriented induction motor (IM) drive using on-line rotor time-constant estimation with a hybrid sliding mode speed controller is introduced in this paper. The estimation of the rotor time-constant is made on the basis of the model reference adaptive system (MRAS) using an energy function; and the estimated rotor time-constant is used in the current decoupled controller, which is designed to decouple the torque and flux in the stator flux field-oriented control. Moreover, a hybrid sliding-mode speed controller, comprised of an integral-proportional (IP) speed controller and a sliding-mode controller with an integral-operation sliding surface, is designed to increase the robustness of the speed control loop. When a sliding mode occurs on the sliding surface, the control system acts as a robust state feedback system. |
