Abstract:	本論文研究目的為研製與發展用於定轉矩區、定功率區和降功率區的高性能寬速度範圍同步磁阻馬達驅動系統，當系統運行於額定轉速之下時，採用了最大功率因數控制，使控制的同步磁阻馬達可以操作在最大的功率因數工作點，當轉速運行於額定轉速之上，則透過新型的電壓角控制器，達到弱磁和每伏特最大轉矩控制來實現寬速度範圍之操作。由於同步磁阻馬達未模式化動態的存在及磁飽和現象，使得其系統具有高度非線性及磁飽和現象，為了強化速度的動態響應，設計出以交軸電流為基礎的適應性互補式滑動模態系統於同步磁阻馬達的速度追隨控制。此外，為了改善同步磁阻馬達的能源成本，提出了一種線上即時的最大功率因數控制器來生成同步磁阻馬達當前的直軸電流命令。另一方面，當馬達轉速操作超過額定轉速，操作於定功率區以及降功率區時，以電壓控制取代電流控制來進一步提升高速區之操作範圍，其電壓控制器產生定子電壓命令的增量值，能迅速地達到最大電壓上限，同時具有每伏特最大轉矩之限制器的新型電壓角控制器，並透過具前饋項的電壓角控制器計算電壓角命令。最後，本研究以32位元浮點運算數位訊號處理器TMS320F28075將適應性互補式滑動模態控制於同步磁阻馬達之寬速度控制，實現於功率4kW的同步磁阻馬達驅動系統，通過實驗結果驗證了所提出之理論的強健性。 ;In order to develop a wide speed range operation of synchronous reluctance motor (SynRM) drive system for constant torque, constant power and reduced power regions, an adaptive complementary sliding mode (ACSM) speed control with maximum power factor (MPF), flux-weakening (FW), and maximum torque per voltage (MTPV) is proposed in this study. Firstly, a conventional FW control system with field-oriented control is introduced. To improve the dynamic response of speed, an ACSM speed controller is derived. Moreover, an online MPF controller is proposed to generate the d-axis current command for the current control mode of the SynRM. Furthermore, the FW voltage controller is employed to produce the incremental value of stator voltage command to achieve the maximum voltage limit. In addition, a novel voltage angle controller with an MTPV limiter is designed to generate the voltage angle command for the voltage control mode. Finally, the proposed ACSM speed control system is implemented in a 32-bit floating-point digital signal processor TMS320F28075 and its robustness and effectiveness are verified by some experimental results.
