中文摘要 | 本文結合一複合型適應速度控制器及一效率控制方法以同時控制感應馬達的轉速 及效率。 首先,採用輸入 / 輸出線性化的控制技巧以使感應馬達的速度動態與磁通動態達 到真正的解耦合,再設計一複合型適應控制器以控制馬達的轉速,並於輕載時,根據轉矩電 流與激磁電流的穩態值計算新的激磁命令電流,以降低感應馬達的功率損失,達到高效率運 轉的目的。 最後利用一部個人電腦為控制主體,將所推導的控制方法實際應用到一 800 瓦 的感應馬達上,實驗結果顯示,本文的控制方法具有相當良好的控制響應,可以同時達到高 性能及高效率的控制要求。 |
英文摘要 | A combination of a composite adaptive speed controller and an explicit efficiency control algorithm is proposed to control the speed and power efficiency of the induction motor in this paper. First, the input-output linearizaton method is used to dynamically decouple the motor speed and rotor flux. Then, a composite adaptive control algorithm is deisgned to control the speed of the induction motor. At steady-state light-load condition, the magnetizing current command is adjusted on the basis of the product of magnetizing current command and torque current command such that the steady-state power loss is minimum. A PC- based experimental drive system has been implemented, and some experimental results are provided to demnstrate the effectiveness of the presented approach. |
