中文摘要 | 在本研究中,首先,依據感應馬達的電壓及電流建立一合適之感應馬達轉速估測 器,然後,將此一估測之馬達轉速作為回授信號,並設計一參考模式適應控制法則,以進行 轉速控制。同時依據 Lyapunov 定理驗證此一轉速控制系統之穩定性。經由模擬結果顯示, 本研究所提之適應性速度控制器不但具有良好之速度控制性能,而且對於馬達機械參數變化 或負載干擾皆具有強健性。 |
英文摘要 | An adptiv controller for an induction motor without shaft sensor is presented in this study. First, an efficient approach to estimate the speed of the induction motor without shaft sensor based on the measured terminal voltages and currents is derived. Then, this estimated speed signal is used as the feedback signal in the speed control loop of the induction motor. Meantime, an adaptive control algorithm is proposed to control the speed of the induction motor. The stability of the wverall system is proved using Lyapunov theorem. Simulation results show that the speed control performances of the proposed adaptive speed controller is satisfactory. Moreover, the proposed adaptive speed controller is robust to the motor mechanical parameter variations and the extemal load disturbances. |
