摘要

手自排變速箱(Automated Manual Transmission, AMT)結合手排變速箱(Manual Transmission, MT)之高效率特性及傳統自排變速箱(Automatic Transmission, AT)之自動換檔的優點，而且開發成本遠低於AT。AMT換檔驅動方式可為油壓式與電控式，其中電控式AMT系統使用直流有刷馬達驅動換檔機構，然而此種馬達具有運轉火花與操作壽命低的缺點，增加AMT系統的維護頻率。為了解決上述之問題，本論文提出永磁同步馬達的AMT換檔驅動系統。
本文之研究目的在於開發永磁同步馬達AMT換檔系統的控制器，此控制器可依據離合器位置驅動永磁同步馬達的位置與速度，達到1.2秒的換檔時間要求。本文首先探討永磁同步馬達的數學模型，其次以Matlab/SIMULINK模擬永磁同步馬達閉迴路控制系統輸出結果，最後完成驅動電路製作。控制核心為dsPIC30F3010，藉此產生脈波寬度調變信號，驅動永磁式同步馬達，進而驗證馬達控制器實作及設計分析是否正確。依據實驗結果，本論文所研製之AMT換檔系統的控制器確實可達成離合器自動控制的功能，且換檔時間低於1.2秒。

The automated manual transmission (AMT) can not only operate as efficiently as the manual transmission does but also can shift gear automatically as the automatic transmission does. In addition, its cost is lower than that of the automatic transmission. The AMT is powered by hydraulic or electromechanical devices to shift gear. The actuator of the electromechanical gear shifting device adopted by the current AMT is a DC brush motor. However, DC brush motor is with spike issue and low durability which results in high maintenance frequency. To solve this problem, this thesis proposes a new AMT system based upon permanent magnet synchronous motor.
The objective of this thesis is to develop the controller of permanent magnet synchronous motor for AMT gear-shifting system to meet the requirement of 1.2 sec. of shifting time. The motor drive is designed and implemented according to the simulation results of a closed-loop control system, which derived by the Matlab/SIMULINK and the developed model of permanent magnet synchronous motor. The control kernel of the motor drive is a dsPIC30F3010 and there by generating PWM control signals for motor drives. The experiment results demonstrate that the developed controller is able to successfully drive the permanent magnet synchronous motor and the shifting time is lower than 1.2 sec.
