摘要

本論文主要研製以DSP來控制飛輪電池充放電模式之系統。由於本實驗中飛輪電池之電動機/發電機模組為永磁同步馬達，因此首先介紹永磁同步馬達動態模型與控制理論。接著說明飛輪電池充放電控制系統的電力轉換電路，主要著重於飛輪發電機穩壓輸出電路，利用Matlab模擬了解電路動作原理，並將其等效成單相Boost昇壓電路來計算輸出結果與實驗結果做比較。而後針對與市電併聯系統進行模擬，利用電流控制器的設計來達到與市電同步的目的，另外使用QFT設計控制器來降低市電回灌之干擾。最後，本文對電動機與發電機兩者互相耦合的系統做探討，作為電路元件選擇的依據。

The objective of this thesis is to use DSP control for flywheel battery. As in this experimental structure the flywheel consists primarily of the permanent magnet synchronous motor. Therefore we first analyze control model of permanent magnet synchronous motor (PMSM). Then we describe the charging and discharging phenomenon of flywheel battery, and introduce flywheel generator output constant voltage circuits. Using Matlab simulation to understand this circuit principles of action, the circuit can be equivalent to single-phase Boost circuit. The circuit can be used to calculate the output results and for comparison with experimental results. For the gird-connected system simulation, we design the current controller for synchronization with gird-connected system, also use the QFT controller to reduce gird-connected interference. Finally, we discuss the motor and generator system coupled to each other, it can be the basis for the circuit component selection.
