摘要

本論文旨在研製一具市電併聯型變流器，應用於太陽能發電轉換系統之最大功率追蹤。本論文控制器採用電流控制型電壓源變流器，搭配最大功率演算法求出變流器之輸出參考電流，透過參考電流與市電回授電流訊號之間的誤差，設計終端滑模電流控制器追蹤太陽能發電系統之最大功率點電流，其優點除提供有限的系統收斂時間與消除直流穩態誤差，亦可減少滑模函數所產生的切跳狀況。為提升控制器的強健性與其可行性，控制器亦考慮被動元件的參數不確定性與外在干擾，推導其強健性能。最後透過數值模擬與實作驗證其控制性能。
在實驗方面，其架構包含太陽能板、市電併聯型變流器與TI DSP TMS320F28335控制核心。系統控制策略皆由軟體程式完成，以減少硬體成本，更增加系統運作之可靠度以及彈性。對未來太陽能市電併聯研究具有貢獻。

This research presents a grid-tied inverter development for PV power generating systems with MPPT ability. The inverter regulates the output power of the PV array system by terminal sliding mode current tracking control with the MPPT algorithm. To efficiently increase the power tracking performance, we design a terminal sliding mode controller TSMC such that the system guarantees the finite-time convergence of inverter current tracking. Moreover, robustness against parameter uncertainties and disturbances are also considered in the controller design such that the controller is suitable for real implementation. Finally, both simulations and experiments are done to verify the feasibility of the proposed controller.
In experiments, a grid-tied PV power generation system is constructed. The MPPT control strategy is implemented by TI DSP TMS320 F28335; therefore, the designed MPPT system not only comes with small size and high reliability, but also is contributive in grid-tied PV power system applications.
