摘要

在太陽能微型電網架構中包含太陽能板、電源轉換器與蓄電池。本篇論文提出以T-S模糊方法去實現太陽能發電系統之最大功率追蹤。而T-S模糊模型可以利用模糊規則將非線性系統拆解成數個線性子系統。而且，穩性定條件則利用Lyapunov方法求得，也就是將控制問題轉換成解線性矩陣不等式。首先利用數值模擬我們可以得到滿意的效果。不過，我們更致力在實作方面的實現。最後，我們建構太陽能發電實驗架構，其中包含SP75太陽能板模組、電源轉換器、類比數位轉換卡(DS1103)與即時介面(dSPACE)。然而，實驗結果達到驗證的效果。

A micro-grid power system consisting of a photovoltaic (PV) array
panel, DC/DC converter, and a battery is considered in this
research. This thesis proposes a T-S fuzzy method to deal with the
power tracking problem of the power generating systems. The T-S
fuzzy model can represent nonlinear systems into fuzzy rules with
consequent part as local linear subsystems. Then, the stability
analysis is carried out using Lyapunov direct method where as the
control problem is formulated into the feasibility of solving a
set of linear matrix inequality (LMIs). The satisfactory
performance is firstly shown by the numerical simulation result.
Then, we focus on the experiment on the hardware realization. To
this end, we establish an experiment environment for the solar
power system, which includes an SP75 solar module, a DC/DC buck
converter, an A/D DS1103 card, and a real-time interface, dSPACE.
Then, the experiment is carried to verify the proposed scheme.
