  • 本文主旨在於研製智慧型微電網併聯多模組變流器之適應性全域滑動模式控制系統,設計獨立供電與市電併網策略,由於該電路為多模組變流器併聯使用,因此控制架構基於主僕控制理論而發展。首先以設計之電路架構規劃各變流器模組基本控制準則,而控制準則在獨立供電情況下是控制變流器模組之輸出電壓以及電感電流,以有效抑制內部迴圈電流的產生。市電併網情況下,則是控制各組變流器之電感電流,加以控制各台變流器之輸出功率及單位功因併網。本文將使用適應性全域滑動模式控制各變流器模組,並使用傳統滑動模式控制及比例積分控制做為比較,且在系統分別於獨立供電模式及市電併網模式之情況下,進行加卸載響應、功率分配以及負載變動之各種狀況進行測試。此外,藉由里亞普諾穩定理論(Lyapunov Stability Theorem)證明整個控制系統穩定,以達到智慧型微電網併聯多模組變流器之高性能獨立供電以及高功因市電併網之目的。本文透過模擬軟體Matlab進行數值模擬分析,並以實作電路驗證本文所發展之適應性全域滑動模式控制應用於智慧型微電網併聯多模組變流器獨立供電與市電併網策略的可行性,其結果為適應性全域滑動模式控制相較於傳統滑動模式控制及比例積分控制更具有強健性,使得電路更快速得恢復至穩定之狀態。


    The main purpose of this thesis is to design stand-alone and grid-connected power supply strategies based on adaptive total sliding-mode control for multiple module inverters in a smart micro-grid. Because of the utilization of multi-module inverters, the control strategy is designed in the sense of the master-slave control theory. As for the stand-alone power supply, the control criterion is to control the output voltage and the inductor current of the inverter module for avoiding the occurrence of inner loop currents. As for the grid-connected power supply, inductor currents in multi-module inverters are controlled for manipulating the output power of each inverter and maintaining the grid connection with a unity power factor. This thesis will apply adaptive total sliding-mode control (ATSMC) frameworks to multi-module inverters, and compare related responses with the ones in traditional sliding-mode control (SMC) and proportional-integral control (PIC) under different operational conditions including loading, unloading, power dispatch changing, load variation, inverter plug-in and shut-down. Moreover, the system stabilities of the ATSMC schemes for multi-module inverters are verified by the Lyapunov stability theorem to achieve the objectiveness of high-performance standalone power supply and grid-connection with a unity power factor. Numerical simulations carried out by the Matlab software and experimental results impelemted in a digital signal processor (DSP) are provided to verify the superiority of the proposed ATSMC frameworks in comparisons with traditional SMC and PIC schemes. As a result, the performance of the proposed ATSMC strategy is more robust than the framework of PIC.
