本文探討矩陣轉換器永磁同步電動機驅動系統的適應性控制器設計及研製。傳統的交流／直流整流及直流／交流變頻的兩級轉換變頻器需要直流大電解電容，穩定輸入側的直流鏈電壓。此電容體積大，需定期更換，並導致輸入電源側諧波大、功因差。本文無使用電解電容以節省空間及降低成本，並達到功因接近1及雙向能量傳送。
另外，為了改善電動機的暫態響應及運轉中受到參數變動影響，本文探討參考模型及自我調整適應性控制器，提升暫態響應、加載響應及追蹤響應，並可增加永磁同步驅動系統的強健性。文中，針對參考模型適應性控制器及自我調整適應性控制器進行優缺點的比較。
最後，採用瑞薩公司生產的DSP，型號SH7237，及英特爾公司生產的FPGA，型號10M16SAU169I7G，共同完成矩陣轉換器開關控制、轉速控制、及電流控制，達成數位化的矩陣轉換器永磁同步電動機驅動系統。相關的實驗結果，說明本文所提方法的正確性及可行性。

This thesis investigates the adaptive controller design and implementation for matrix-converter based IPMSM drive systems. The traditional AC/DC rectifier and DC/AC inverter include two-stage energy conversions and a huge DC electrolytic-capacitor, which required large volume and regular maintenance, to obtain a stable DC-link voltage. In this thesis, no DC electrolytic-capacitor is used in order to reduce the space and cost, and achieve near unity power factor and bidirectional energy conversion.
In order to improve the transient responses and reduce the sensitivity of the variations from system parameters, two adaptive controllers including a model-reference adaptive controller and a self-tuning adaptive controller are proposed. The proposed adaptive controllers can improve the transient responses, load disturbance responses, tracking responses, and robustness of the IPMSM drive system. Several comparisons between the model-reference and self-tuning adaptive controllers are discussed.
A digital signal processor, manufactured by Renesas Electronics Corporation, typed SH7237, and an FPGA, manufactured by Intel Company, typed 10M16SAU169I7G are used to execute the control algorithms of the switching control of the matrix-converter, speed control, and current control to achieve the matrix-converter based IPMSM drive system. Experimental results validate the feasibility and correctness of the proposed methods.
