- 中文摘要: 間接式磁場導向控制感應馬達驅動系統雖已能取代直流馬達驅動系統,使用在需要高性能的工業應用上。然而,其性能容易受馬達參數變化的影響。因此,為求理想的磁場導向解耦控制,控制器的參數必須加以調適,但這是難以達到的。本文提出一數位式模式參考適應速度控制器,應用在間接式磁場導向控制感應馬達上,使感應馬達參數變化時,不致於使其控制性能變差。因為一般很難推導出精確之感應馬達驅動系統動態模式,本文採用隨機模式識別技巧,由取樣之輸入/輸出資料估測驅動系統之動態模式。所提之適應速度控制器,僅需用到參考模式的訊息及受控體的輸出信號,且不需做線上參數鑑別。因此,其容易被應用在馬達驅動系統上。文中將推導此適應控制器的控制法則,並先以模擬確認其可行性及控制效果。然後再實際製作驅動系統及控制器,並以一些實測結果來驗證所提適應控制器之控制性能。
- 英文摘要: In this paper, a discrete model reference adaptive speed controller for indirect field-orientedinduction motor drive is designed and implemented. No on-line parameter identification is needed, andonly information for the reference model and the plant output are required for the control. Hence, theproposed controller is easy to implement practically. To design the proposed adaptive controller, the dy-namic model of the drive system is estimated from the sampled input/output data using the stochasticmodelling technique. Having tested the performance of the proposed controller by computer simulation,the hardware of the drive system and the software of the microprocessor-based adaptive controller areimplemented. Finally, some experimental results are given to demonstrate the effectiveness of the propos-ed controller.
