- 中文摘要: 在本研究中,我們使用一個以傳輸電腦為基礎的平行控制系統,實現一個數位式交流感應伺服空間向量調變電流控制器。此電流控制器為一在d-q靜止座標系工作的比例積分控制器;並具反電動勢前餽補償,此反電動勢可由在向量控制之下的轉子磁通模型計算出,且所提空間向量脈寬調變實現方法計算簡單。此電流控制與脈寬調變方法乃以兩個IMS T800-20傳輸電腦來實現,使其整個控制法則的執行時間在100μs內完成。本方法乃應用於-800 W 的交流感應伺服馬達,實驗結果顯示其有效性。
- 英文摘要: In this work, we design and implement a discrete-time current controller with the space vectorpulse width modulation (SVPWM) scheme for ac induction servo drives employing a transputer-basedparallel control system. The current controller is a PI controller with feedforward back emf compensationin the d-q stationary reference frame. The back emf is determined based on the rotor flux modelunder vector control. A simple implementation method for the SVPWM scheme is presented. The currentcontrol and pulse width modulation scheme is implemented by using two IMS T800-20 transputers, inwhich the execution time of the overall control algorithm can be accomplished within 100 μs. Experimentalresults using an 800 W AC induction servo motor show the effectiveness of the proposed controlmethod.
