摘要

本文針對直驅電梯牽引用之永磁同步馬達研製適配之馬達驅動裝置，首先於Matlab之Simulink環境建構模擬系統作為控制策略分析與設計之參考。隨後以一只微處理器研製具有向量控制之全數位馬達驅動系統及探討驅動器滿足電梯運動控制所需具備之特性。提出改善馬達於低速之轉速估測方法以提高電梯於低速運轉之舒適性。
另外，為滿足電梯馬達高速運轉之電壓需求，提出具有較低電壓諧波之三相獨立電流控制之三次諧波注入過調變策略及具有電流控制過飽和方法來提升驅動器輸出電壓有效利用率。最後經由實際電梯驅動與配機過程驗證本文所提控制策略之有效性。

The purpose of this thesis is to develop a PMSM motor drive for direct-drive elevator application. In performing the analysis and design of control strategies, a simulation environment based on Simulink is built-up firstly. To facilitate the studies performed in this thesis, a microprocessor-based vector control PMSM motor drive is constructed. Then the configuration and characteristics of elevator are overviewed. Suitable control methods are also established and fully digitally implemented by assembly language in the microprocessor-based drive.
In this thesis, a speed estimation method for motor is presented to improve the low speed performance of the traction motor as well as to let the passengers of elevator be more comfortable. Besides, how to increase the output voltage utilization of motor drive is investigated. Then a third-harmonic voltage injected method, and a over-saturated current control method are proposed to fulfill the voltage requirement of drive. Finally, some experimental results have confirmed the validity of the proposed methods in the motor drive for direct-drive elevator application.
